Indoor Magnetic Instrument Current Transformer Medium Voltage
Introduction
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 circuitry from the high voltages or
currents. The primary winding of the transformer is connected to
the high voltage or high current circuit, and the meter or relay is
connected to the secondary circuit.
Instrument transformers may also be used as an isolation transformer so that secondary quantities may be used in phase shifting without affecting other primary connected devices.
Current transformers (CT) are a series connected type of instrument transformer. They are designed to present negligible load to the supply being measured and have an accurate current ratio and phase relationship to enable accurate secondary connected metering.
