PMT20010 Instrument Transformer Comparator





PMT20010 Instrument Transformer Comparator

The PMT20010 Comparator is an automatically balancing bridge that measures the accuracy of instrumentation potential and current transformers.

Large, backlit, easy-to-read numeric LCD digits are augmented by a colour TFT graphical LCD panel to display measurements of ratio error, ratio correction factor, phase error in centiradians or minutes, excitation voltage, excitation current, accuracy class and the true test circuit burden.
