The CT PT Tester is primarily designed for field testing of Protection Class (P Class) CTs and PTs. Key test functions include excitation characteristics, transformation ratio, polarity, demagnetization (Degauss), 5% and 10% error curves, secondary circuit verification, power frequency AC withstand voltage tests, and secondary burden measurement.
The instrument features an LCD interface and a built-in miniature printer for immediate on-site reporting. It also supports data export via USB flash drive for further analysis and reporting on a PC, ensuring straightforward and convenient operation.
