Instrument Transformer Basic Technical Information and ...

instrument transformer can safely withstand between its primary and secondary winding and between its primary or secondary winding and ground (core, case or tank) without a breakdown in the insulation. Industry standards have established insulation classes ranging from 600 volts up through 545 KV.

Voltage Instrument Transformer (VT)

Instrument transformers. Instrument transformers are primarily used to provide isolation between the main primary circuit and the secondary control and measuring devices. This isolation is achieved by magnetically coupling the two circuits. ... Figure 1 - Voltage transformer circle diagram (fan curves)

Instrument transformer

Instrument transformers are high accuracy class electrical devices used to isolate or transform voltage or current levels. The most common usage of instrument transformers is to operate instruments or metering from high voltage or high current circuits, safely isolating secondary control circuity from the high voltages or currents.
