Which of the transformer is used as instrument transformer?

Current transformer 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.

What is use of instrument transformer?

Instrument transformers are special transformers used to measure voltages and currents while insulating measuring and control devices from the primary circuit.

What is instrument transformer CT and PT?

Such specially constructed transformers with accurate turns ratio are called as Instrument transformers. These instruments transformers are of two types – (i) Current Transformers (CT) and (ii) Potential Transformers (PT).

What principle makes the instrument transformer working?

law of electromagnetic induction
What is the working principle of Current Transformer? The current transformers operating principle is based on the law of electromagnetic induction. With a certain number of turns, the voltage from the external network is supplied to the primary power winding and overcomes its total resistance.

What is the definition of an instrument transformers?

Definition of instrument transformers. Instrument transformers are current and voltage transformation devices that are used to step down the transmission and distribution line voltages and currents to levels that can safely operate measuring instruments, protection devices and control relays by isolating it from the supply voltages.
