WebThe MRCT can be configured to include functionality for performing an excitation test on CTs using DC voltage, allowing measurement of knee points on CTs up to 30 kV. Additionally, the MRCT can be configured to test VTs and single phase relays. The MRCT simplifies testing by automatically calculating ratio errors, saturation curves, and knee ... WebJun 17, 2024 · They are devices that measure the voltage and frequency in a circuit. Like CTs, PTs are needed because the voltage in a circuit is much higher than the relay can handle, so they step it down to a much lower level for the relay. Switching Device. The switching device opens (turns off) or closes (turns on) the circuit.

VTs generally step down the higher voltage to a lower voltage so that it can be measured easily with the standard voltmeter. Such transformers possess a higher number of turns on a primary side and smaller number turns on the secondary side.
WebThe CTs and VTs were calibrated, and correction coefficients for fixed magnitude and phase errors were known. Table 1 shows the results using the existing method when no random errors were present in the simulated measurement system. The bias errors in the measurements of all the CTs and VTs were corrected.
