We have over 50 years of experience in designing and manufacturing Current Transformers for both metering and protection applications. Every single current transformer manufactured in our East Kilbride plant is also individually tested at our factory. This way, we ensure our CTs comply with British, European, and international standards.
Our speciality is custom solutions. At the moment, we have over 60,000 different designs, so we are quite confident we have the right unit for you. And if we do not, you can rest assured our engineers have the knowledge, experience and skills to find the perfect current transformer for your project. This flexibility is why we are well known in the industry as the "go-to CT/VT guys".
Designed to International Standards
Whether your project is for a utility network, an industrial facility, a marine installation, a renewable energy project, or an AI data centre, ITL designs and manufactures current transformers to meet recognised international standards. Our engineering team can supply products compliant with IEC, IEEE, Australian and UL requirements, helping customers meet local regulations and project specifications across global markets.
Typical standards include:
- IEC 61869-1 – Instrument Transformers – General Requirements
- IEC 61869-2 – Current Transformers
- IEEE C57.13 – Instrument Transformers
- AS 60044 / AS IEC 61869 – Australian Instrument Transformer Standards
- UL Recognised Components for applicable low-voltage products
Metering Current Transformers
Designed in accordance with IEC 61869-2 and IEEE C57.13, our metering CTs provide highly accurate measurement for revenue metering, energy monitoring and power quality applications.
Protection Current Transformers
Protection Current Transformers are designed and manufactured to internationally recognised standards, including IEC 61869-2, with protection classes 5P, 10P, PX, TPX, TPY, and TPZ, where specified. Additionally, IEEE C57.13 ensures reliable relay operation under fault conditions.
Split Core CTs
Available with specifications to IEC, IEEE and selected UL recognised requirements where applicable.
Ring Type CTs
Manufactured to IEC, IEEE/ANSI, AS and CAN / CSA specifications for worldwide installation.
