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.
