MODEL 590K: FULL LOAD CVT ANALYZER

A comprehensive portable CVT test system. Test CVT’s rated to 550kV rated metering ratio accuracy to 0.08% to 0.1% and rated protection ratio accuracy from 0.15% to 0.5%. Measures up to 3 CVT secondary’s at one Measures CVT ratio and phase errors at different burdens power factors and test points. Multiple test point standards to choose from.

The model 590K will fully test a CVT and display its Error of Magnitude (EM) and Error of Phase (EP) at specific voltage and burden test points with an accuracy to 0.05% to 0.08% and on a protection winding from 0.15% to 0.5%.

The test is performed by applying up to 3kV to the primary input of an un-serviced CVT. A secondary switching arrangement is used to support connections for different types of tests. Also an auto ranging feature allows the 590K to measure many kinds of CVTS whether part of its database or not by using sophisticated DSP hard-ware to perform the CVT modelling and the automated test and measurement calculations.
