Voltage Transformer testing

Voltage transformer testing is a crucial aspect of ensuring the accuracy and reliability of voltage measurements in electrical systems. Voltage transformers, also known as potential transformers (VTs), are integral components used to scale down high-voltage levels for safe and accurate measurement, protection, and control applications. The testing of voltage transformers involves a range of diagnostic procedures to verify their performance and condition. These tests typically include ratio testing, which confirms the VT’s ability to reduce voltage accurately, insulation resistance testing to assess the quality of insulation, and burden testing to evaluate its ability to supply the necessary output to connected devices.
