Portable and light weight for testing pontential and current transformers down to as low as 0.02% accuracy offline in the field with primary side voltage / current out of service. Both 50Hz and 60Hz versions.
Tests for C.T. current and phase error from 2.5 / 5 up to 75,000 / 5 or 15,000 / 1
Tests P.T. turns ratio and phase error up to 300k V / 110 V.
Calculates overall C.T. errors under load from admittance measurement on secondary winding. (Does not require expensive primary current injection testing)
Calculates offline admittance at 1.6kHz. This can provide a blue print to be used as reference for future routine live C.T. tests with Red Phase Model 505B. The model 505B carries out live Admittance tests rapidly during normal operation with the primary 50/60Hz current present; Does not interrupt supply.
Measures the burden of C.T. and P.T. secondary circuits to ensure C.T. and P.T. not overloaded.
User is able to create their own set of injection and burden test points.
CT batch testing possible
Is able to store up to 1000 C.T. and P.T. records each.
Able to provide intelligent class (pass or fail) results assessment and also provide best class fit determination.
Able to upload and download information to a PC via USB interface
