The Role of Instrument Transformers in China s Relay Protection System

Instrument transformers (ITs) are specialized transformers whose main role is to step down high currents or voltages in power systems to safe, standardized levels for metering, protection relays, SCADA, and control circuits, while maintaining proportionality and phase relation. This step-by-step guide describes the basic concept of double pulse testing (DPT) and the necessary measurement setup and provides an overview of the parameters influencing the measurement. This. The purpose of this document was to get to know the theory behind instrument transformers in substations and to create a calculation template in Microsoft Excel which would simplify the current transformer calculation process. The way of implementing different calculations to be print ready to. Instrument transformers can be categorized into two main types: Current Transformers (CTs) and Voltage Transformers (VTs). Each type serves specific functions in power systems.
