A correction can be selected for either copper or aluminium windings.\u003c\/p\u003e\n\u003cp\u003eWhen used for automatic “Heat Run” tests, measurements are made at preset time intervals and an internal algorithm is used to calculate the resistance at t=0. The transformer is made safe after testing by discharging stored energy into the 5896C attenuation resistor and varistors. Only a negligible residue will remain when the discharge warning light indicates that it is safe to remove the test leads.\u003c\/p\u003e\n\u003cp\u003eThe 5896C uses the four-wire measurement technique to eliminate the effect of the resistance of the test leads. By using the dual inputs of the 5896C it is possible to measure both a low voltage and the high voltage winding of a transformer at the same time. This can greatly reduce the time taken to produce cooling curves with an added advantage that the stability of the low voltage winding measurement can be improved when the high voltage winding is energised by the 5896C at the same time.\u003c\/p\u003e\n\u003cp\u003eThe 5896C can be used to control the transformer tap changer.
