ITL have over 40 years of experience in designing & manufacturing a range of high quality, voltage transformers in three different frame sizes for both measuring and protection duties. Transformers are designed to comply with the requirements of IEC 61869-3 or other international standards as required to satisfy most Low Voltage applications.

Low voltage instrument type voltage transformers are configured as single phase measurement or single phase protection.

Three phase voltage transformers measurement or protection are normally connected star / star, utilise the same standard frames in sets of three and are mounted on a common base thereby ensuring magnetic equality between phases.

Instrument Transformers also have a range of medium voltage transformers, either epoxy resin cast or oil filled impregnated paper type, suitable for indoor and outdoor installation.

Single Phase Voltage Transformers

ITL design and manufacture 1PH units in the United Kingdom. All our voltage transformers conform to IEC 60044-2 and other standards are available upon request.
This robust and compact constructed single phase measurement voltage transformer comes in 3 standard frame sizes and all standard voltages between 55 - 480 volts primary and 63.5 - 240 volts secondary.

Each transformer is individually tested and is traceable to NPL (National Physical Laboratory).
