Challenge of Substation Auxiliary Power Supply

The Benefits of Permanent Partial Discharge (PD) Monitoring for Gas-Insulated-Switchgear & Power Transformers

Gas Insulated Switchgear (GIS) is a crucial component of electrical power systems, providing a compact and reliable solution for controlling and distributing electricity. To ensure the reliable operation of GIS, permanent partial discharge (PPD) monitoring plays a vital role. Here are five key benefits of implementing PPD monitoring for gas-insulated switchgear:

  1. Early Detection of Insulation Defects: PPD monitoring allows for the early detection of insulation defects within the GIS. Partial discharges are localised electrical discharges that occur within the insulation materials, indicating potential weaknesses or faults. Any abnormalities can be detected early by continuously monitoring and analysing PPD signals, enabling timely maintenance or repair actions.
  2. Preventing Catastrophic Failures: Insulation defects, if left undetected and unaddressed, can lead to catastrophic failures in gas-insulated switchgear. These failures can result in power outages, equipment damage, and even safety hazards. PPD monitoring helps prevent such failures by providing real-time insights into the condition of the insulation, allowing for proactive maintenance and minimising the risk of unexpected breakdowns.
  3. Optimised Maintenance Strategies: Traditional maintenance practices for gas-insulated switchgear often involve periodic inspections or time-based maintenance schedules. However, these approaches may lead to unnecessary maintenance or overlook critical issues. PPD monitoring enables condition-based maintenance, where maintenance activities are planned based on the actual condition of the insulation. This approach optimises maintenance strategies, reduces downtime, and extends the lifespan of the GIS equipment.
  4. Improved Asset Management: PPD monitoring facilitates better asset management for gas-insulated switchgear. Continuous monitoring of the insulation condition collects valuable data on partial discharge activity over time. This data can be analysed to gain insights into the overall health and performance of the GIS equipment, identify trends, and help make informed decisions regarding asset maintenance, replacement or upgrades. This proactive approach enhances the reliability and efficiency of the power system.
  5. Enhanced Safety and Reliability: PPD monitoring significantly enhances the safety and reliability of gas-insulated switchgear installations. By actively monitoring and managing insulation defects, the risk of electrical faults, arc flash incidents, and equipment failures is minimised. This ensures the uninterrupted supply of electricity, reduces the potential for accidents, and improves overall system reliability.

In conclusion, permanent partial discharge monitoring for gas-insulated switchgear offers several significant benefits. From early defect detection and preventing catastrophic failures to optimised maintenance strategies, improved asset management, and enhanced safety and reliability, PPD monitoring is a valuable tool for ensuring the efficient operation of GIS installations.

Benefits of Custom Designed Current Transformers for Electrical Switchgear Manufacturers

Benefits of Custom Designed Current Transformers for Electrical Switchgear Manufacturers

Current transformers (CTs) play a crucial role in electrical switchgear systems by accurately measuring electrical currents. While standard CTs are readily available, there are significant advantages to opting for custom-designed CTs tailored specifically for electrical switchgear manufacturers. Here are five key benefits of custom-designed CTs:

  1. Enhanced Accuracy: Custom-designed CTs can be manufactured to match the specific characteristics and requirements of the switchgear system or existing installed CTs. By taking into account factors such as the primary current range, burden impedance (VA), and accuracy class, we can achieve superior accuracy in current measurement. This ensures robust and reliable performance, enabling accurate power monitoring and protection of electrical equipment.
  2. Optimal Size and Form Factor: Electrical switchgear systems often have unique space constraints due to design considerations or the facility's layout. Custom-designed CTs allow Instrument Transformers Limited (ITL) to manufacture transformers that fit perfectly within the available space, maximising the efficiency and compactness of the switchgear design. This customisation ensures seamless integration and minimises the need for additional modifications or adjustments.
  3. Tailored Ratings and Specifications: Standard CTs may not always meet the specific rating requirements of electrical switchgear manufacturers. Custom-designed CTs enable manufacturers like ITL to choose the appropriate ratings, such as current ratios, accuracy classes, and thermal limits, to match the unique characteristics of their customers' switchgear systems. This customisation ensures optimal performance and avoids over or under-sizing of current transformers.
  4. Improved Safety and Reliability: Custom-designed CTs can be engineered with advanced safety features and protective measures, enhancing the overall reliability of the switchgear system. Manufacturers can incorporate additional insulation, thermal monitoring devices, short-circuit protection, and other safety mechanisms to mitigate risks and prevent potential failures. This customised approach enhances the safety of personnel and equipment, reducing the likelihood of electrical accidents or downtime.
  5. Cost-Effective Solution: While custom-designed CTs may involve an initial investment in design and engineering, they can ultimately provide a cost-effective solution for electrical switchgear manufacturers. By tailoring the CTs to match the specific requirements and constraints of the switchgear system, manufacturers can eliminate the need for costly modifications, minimise downtime, and optimise energy consumption. Additionally, custom CTs' enhanced accuracy and reliability contribute to efficient maintenance, reducing long-term operating costs.

In conclusion, custom-designed current transformers offer several advantages to electrical switchgear manufacturers. From enhanced accuracy and tailored specifications to improved safety and cost-effectiveness, these customised solutions empower ITL customers to optimise their switchgear systems' performance, reliability, and efficiency. Electrical switchgear manufacturers can achieve superior results by partnering with an experienced transformer manufacturer such as Instrument Transformers Limited (ITL) and leveraging our expertise in customisation.

What’s best: “TR CU” or “EAC” Certification?

Sometimes we get questions regarding TRCU & EAC and which is best. I thought it would be good to try to help our customers with this short post on what they are and how they are interpreted.

The compliance with current standards of the technical regulation is critical for importing products subject to conformity to Russia and other Eurasian Economic Union member states.

Many manufactures are confused by the conformity assessment process with what's the difference between TR CU Certificate and EAC Certificate?

It is two different names for the same process of conformity assessment, whereby both terms are wrong or incomplete and misleading translation.

The background of the names is historical when the standardisation originated in the former Soviet Union. The new system of standardisation covers a large part of Eurasia.

This system was known as GOST an abbreviation of "Государственный Стандарт", which translates into "state-standard". and was umbrella standardisation in the Soviet economy. 

With the disintegration of the Soviet Union in the 1990s, several of the member states started developing their standard and conformity assessment procedures, to simplify the confusing GOST system.

Around 2002/2003, the "On technical regulation" law passed in the Russian Federation declaring that new technical guidelines are developed. Subsequently, the "Technical Regulation" "TR" formed containing fixed requirements for products, services & manufacturing processes.

Russia, Belarus & Kazakhstan founded their Free-Trade-Association which eventually became known as a "Customs Union" "CU". Allowing a single technical regulation to facilitate the sale of goods & services between the member countries underpinned by a common standard "TR CU"

Later when Kyrgystan & Armenia joined an opportunity to enhance standardisation further, Europes "CE" mark would be an appropriate model in which to combine with, developing into what today is the "EurAsian Confirmaity" or EAC certificate.

Now EAC is the proper standardised name but is commonly interchanged when TR CU, GOST standard is mentioned/required.

Transformers supplied from ITL destined for the EurAsian market will have the correct EAC certification attached. If you need a copy of our certificate for your project, feel free to reach out to us at marketing@itl-uk.com where one of our team will assist.

Getting the best value out of your CT purchase (Pt.1)

Bit of a wordy headline but as part of my getting the best value out of your purchase series, in this weeks post I am focussing on Metering or Measurement Current Transformers.

When a customer asks for a quotation, he/she may have a price in mind. That might be based on previous purchases or a hunch, but none the less a price is ingrained.

Current Transformers (CT's) while a relatively simple product in nature, sometimes customers are not always sure about what they need and give you a specification that is wildly over-specified for the application. As a CT manufacturer, we understand you are not experts. However, loaded with some knowledge on the factors that can influence price, then there is an opportunity to extract the higher value from your purchase.

RATIO: Primary (input) & Secondary (output) Current Ratio (e.g. 200/5A)

VA: Total instrument burden, including the length of any pilot wires along with square mm of the cable (e.g. 4sqmm).

CLASS: Accuracy required for operation (Tariff, Measurement or Indication

DIMENSIONS: Maximum & Minimum ( the space you have available to fit the current transformer, e.g. for a ring-type Inside Diameter ID, Outside Diameter OD, Axial Length AL).

  1. By specifying a higher VA or ACCURACY CLASS than necessary will likely result in a more expensive product.
  2. Cost generally increases as the Current Transformers inside diameter (ID) increases.
  3. 1A Current Transformers are typically more costly than 5A, why I hear you say - 200/1A has 200 turns of copper whereas 200/5A has 40 turns of copper thus an 80% cost saving on copper, not to mention a reduction in the overall dimensions).
  4. Potentially unnecessary accessories such as mountings which are chargeable extras. (Most customers have their own preferred and cheaper method of mounting inside the switchgear).

Considering the above plays a big part in getting the right product for the right price.

For this post, we will consider IEC 61869 as the default standard, as this is our usual customer requirement. However, should you need IEEE/ANSI or AS (Australia) we are just as at home with these specifications?

IEC 61869 standard:

There is also Class 3 & Class 5 but rarely used, most people opting for a Class 1 as a better alternative.

High accuracy classes like 0.2s & 0.5s often require a special type of core material which in itself very expensive, so this accuracy class should only be selected when a tariff application is required.

We appreciate our customers are not specialist in transformer design but have found that one of the most common misunderstood factors about specifying a current transformer (CT) is the Burden or VA. For example, if you double the burden from 5 to 10VA, you will increase the electrical steel content and thus have a significant impact on the unit price so you must get this right.

The burden is the load imposed on the secondary of the CT at rated current and is measured in VA (product of volts and amps). The accuracy class applies only to loads at rated VA and below, down to one-quarter VA. The burden on the secondary of a CT includes the effect of pilot leads, connections etc. as well as the instrument burden itself.

In situations where the meter is remote from the current transformer, the resistance of the pilot wires may exceed the meter impedance many times in these cases it is often economical to use 1 amp meters and CTs.

The diagram shows the burden imposed on the CT due to a run of pilot wire, so a pilot loop of 2.5mm2 wire, 60 metres long (30 metres distance) has a load of 12.5 VA on a 5 amp CT but only 0.5VA on a 1 amp CT.

Typical Meter Burdens (depending on the pilot lead length):

Moving iron meter 1-2VA

Moving coil meter 1-2.5VA

Digital instrument 1-5VA

Maximum demand indicator 3-6VA

Can you use a LV CT in MV & HV Environment?

Can a Low Voltage Current Transformer (CT) be used in a Medium or High Voltage application? Surprisingly, it is a question we get a few times a year and thought it would be beneficial to put this out.

Firstly we must understand the configuration of the switchgear. For example, if the switchgear has a system voltage of 12kV and the CT will be installed on the bare busbars in the medium voltage section. Then yes you will need a CT that's fully rated, and generally, that's where the thought & decision process ends.

But let us dig a little deeper. If the CT is to be installed directly on medium voltage busbars, accordingly it must have an insulation level at least equal to that of the system/cubicle. However, if installing a CT on the medium voltage cable (which is already insulated), in this case, the CT can be a low voltage type (e.g. insulation level 0.72kV) as the cable provides the medium voltage insulation. It is this element that is missed by design engineers and as a result, adds unnecessary cost to the switchgear.

Another scenario is a neutral current transformer, typically on outdoor installations where the CT needs to be installed on an MV or HV system but on the neutral circuit. As such, it will not see the higher MV & HV voltages, so it's possible to use a lower insulation rating for the current transformer. It is critical to note on an MV or HV system were the CT will see "line voltage". Then a fully rated insulated current transformer will be required.

Depending on its рurроѕе it can be classified into Current аnd Cоnѕtаnt current, variable аnd соnѕtаnt vоltаgе.

Insulation iѕ оnе оf thе mоѕt important qualities thаt a trаnѕfоrmеr hаѕ, often under-appreciated. In fасt, the durability and ѕtаbilitу of a trаnѕfоrmеr highlу depend upon the рrореr application and utilisation оf the insulation mаtеriаlѕ рrеѕеnt within it.

Understanding the transformer application is key to understanding what insulation materials to use. In Power Transformers insulating рареr аnd cardboard are the twо main insulating mаtеriаlѕ used for isolating рrimаrу and ѕесоndаrу windingѕ with thе mаin соrе. Whereas in some low and medium voltage applications Epoxy or Polyester Resin systems protect while in others a plastic case, polyester tape or crepe paper are most suited.

In the end, insulation plays a vital role in the operation of a transformer; getting it wrong can be expensive.
