GF1060C SMART CT & VT COMPARATOR

CT & VT comparator

The GF1060C CT and VT comparator is a multifunctional, high-precision current and voltage transformer comparator. It is used to compare the secondary current signal or secondary voltage of a device under test or the digital information of a non-conventional transformer with the reference signal of a standard transformer. It is suitable for testing conventional electronic and non-conventional digital current & voltage measuring transformers. GF1060C comparator is strictly in conformity with IEC60044, IEC 61869, ANSI/IEEE C57.13, NBR6855 standards etc.
