Présentation du produit
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.
