Instruments for transformer testing

Instruments for transformer testing are intended for checking the technical parameters of the current transformers and voltage, without de-energizing them. Instruments make it possible to measure the admittance, the transformation ratio, the phase shift of the currents of primary and secondary windings, the current and the voltage. So they [mozhgut] to determine the full-load saturation curves of the secondary winding of transformer and to produce the demagnetization of wires.
