The STRT-100 is designed to test all power, instrument (CTs and PTs), and distribution transformers without the need of traditional high voltage excitation. With true three phase output voltage , testing is up to five times faster than previous phase-by-phase switching single instruments, easier to test phase shift measure ment, vector recognition, phase angle deviation, excitation current(Optional), winding balance.
