History of ITL

Known affectionately as the "CT & VT guys" established in 1973, Instrument Transformers Ltd (ITL) has expanded nationally and internationally such that we are now an internationally known name in the field of power measurement and protection. Since our inception we have been located in East Kilbride, Scotland specialising in the design and manufacture of low voltage current transformers for electricity utilities, switchgear, panel board and generator manufacturers.

By supplying a wide range of Current Transformers and Voltage Transformers for accurate measurement, control and protection of Low Voltage, Medium Voltage

More than 20 years old. A bit weathered but still going strong!

and High Voltage electrical power systems, and continuing to grow our product lines with our global partners. Adding instrument transformers with insulation levels of 11kV, 17.5kV, 24kV, 33kV, 66kV, and 72.5kV with 145kV added in 2009.

2013 has seen ITL move a short distance to new facility allowing a doubling of capability for Production, Design & Administration. As part of the project our facilities team have been busy and have added a second testing zone which has allowed us an increase in our testing capabilities:

  • Second 2000A low current source
  • 20kA high current source
  • Voltage transformer accuracy testing up to 36kV
  • Power Frequency up to 100kV
  • Three Frequency Generators with 60Hz, 150Hz & 400Hz ability

The hub of our activities, manufacturing has also had additional investment with a new dual head winding machine, making it possible to wind & insulate at the same time for transformers with inside diameters greater than 700mm.

Going forward, the use of information technology will also play a big part of our continued growth with virtualisation of our network servers and enhanced remote working for our sales & engineering teams in Q2 2013.

Q4 of 2013 has seen the roll out of our wireless Shop Floor Data Collection system allowing accurate process time measurement ensuring that we can continue to be the most cost competitive solution provider.

Not restricting our growth activities to Low Voltage & Medium Voltage. Working with one of our Low Cost Economy partners we have introduced to the European market a range of OIP type High Voltage Current Transformers, Voltage Transformers & Combined Transformers up to 400kV.

Focused on Continuous Improvement in Process, Product and People we listen to our customers' needs and provide the most technically and commercially optimum solution.

It is a testament to our business owners & successive management teams that has embraced and imparted such noble values as integrity, honesty and empathy to everyone that has contact with our company.
