An instrument transformer is a type of transformer used in electrical power systems to transform currents or voltages from high levels to standardized, measurable values suitable for instruments and relays.These transformers are crucial components in power systems for metering, protection, and control applications.There are two main types of instrument transformers: current transformers (CTs) and voltage transformers (VTs or PTs).

CTs are used to transform high currents on the power system into proportional and standardized current values that can be safely measured by instruments.

They consist of a primary winding connected in series with the power line carrying the high current and a secondary winding connected to measuring devices.The ratio of primary to secondary turns determines the transformation ratio.

CTs are widely used for current measurement in ammeters, relays, and protective devices.      They help monitor and protect power systems by providing accurate representations of current flow.

VTs are designed to transform high voltages on the power system into standardized, lower voltage levels suitable for measurement and protection devices.

Similar to CTs, they consist of primary and secondary windings.The primary winding is connected across the high-voltage power line, while the secondary winding is connected to voltage measuring instruments.

VTs are used for voltage measurement in voltmeters, protective relays, and other devices requiring a scaled representation of system voltage.

Instrument transformers are designed for high accuracy to ensure precise measurements for monitoring and

They provide electrical isolation between the high-voltage primary circuit and the low-voltage secondary circuit to enhance safety for connected instruments.

The secondary current or voltage values are standardized to common values, such as 1A or 5A for CTs and 110V or 220V for VTs.

Instrument transformers play a crucial role in ensuring the safe and accurate operation of instruments and protective devices in power systems. They enable effective monitoring, control, and maintenance of electrical networks.
