Transformer Turns Ratio Meter, 34Vrms excitation voltage 0.8 → 2000 ratio range

Transformer Turns Ratio Meter. RS Pro RS1660 Transformer Turns Ratio Meter. The turns ratio test is an AC low voltage test which determines the ratio of the high voltage winding to all other windings at no-load. The turns ratio test is performed on all taps of every winding. Features and Benefits. Large backlit display Ten Test Frequencies (50 Hz → 400 Hz) Displays turns ratio, deviation, secondary output, excitation voltage and current, phase angle and nameplate transformer/VT/CT values in one page for easy transformer quality interpretation Checks for live test points, short circuit, open circuit and reverse polarity before each measurement. Message is displayed to warn users (checking is not performed once measurement starts) Wireless blue tooth communication with PC Select filter to remove field noise (slow, normal, fast) Auto-Power Off with programmable time Built-in calendar clock
