The Raytech TR-SPY Three Phase Meter automatically measures Turns Ratio, Voltage Ratio, Excitation Current and Vector Phase of transformers
All connections of the various transformer configurations are accomplished internally. This system is very easy to use and operate on all configurations of single and three phase transformers.
This is a fully automatic, rugged and portable instrument that provides very precise and repeatable measurements.
