PRECIMEASURE

The fully sealed liquid expansion in the system provides a self powered indication and operation to theinstruments, and does not require any trimming or other periodic adjustments.

Instruments are fully compensated for ambient temperature.

The WTI instruments have a built in Thermal imaging system for transformers hot spot indication.

The WTIs are provided with gradient adjustment through a shunt for CT secondary input (1A to 5A).

Instrument cases are aluminium die casted and polyester powder coated. Each instrument hasanti vibration mountings and are provided with projection mounting clamps.

A maximum pointer facility is provided, can be reset from outside.

All switch contacts are potential free micro switches
