Electrical Calibrator Instrument

Three phase variable source for testing energy meters , transducers. Creates various load conditions such as lag, lead. creates harmonics. Manual control as well as pc control.

Full-featured, not only satisfy the test requirements of various CTs (include TP class), such as the excitation characteristics (i.e., volt-ampere characteristics), ratio, polarity, secondary winding resistance, secondary burden, ratio error and phase displacement, but can also be used for the tests of various PTs, including excitation characteristics of the electromagnetic unit, ratio, polarity, secondary winding resistance, ratio error and phase displacement
