Voltage Transformers

Designing & manufacturing a range of high quality, voltage transformers in three different frame sizes for both measuring and protection duties. Transformers which are designed to comply with the requirements of IEC 61869-3 or other international standards as required can be supplied 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, mounted on a common base, thereby ensuring magnetic equality between phases.

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

Single Phase Voltage Transformers

Designed and manufactured in the United Kingdom and conforming to IEC 60044-2 with other standards 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).
