Load resistors to raise the secondary load of current transformers, model WSR60 - 1

FAGET loadresistors for current transformers Diffrent to the old electro-mechanical devices the new, static kWh-meters are characterised by a significantly lower power consumption. This effect holds the risk of charging the current transformer with a burden below the minimum value. Subject to standard IEC60044-1, the connected burden must obtain a value between 25% and 100% of the rated burden. Thereby, a more favourable instrument security factor is achieved and the class accuracy ensured. The load resistors have been specially developed to bring the charge of a current transformer within 25% and 100% of the value mentioned on the type plate of the power transformer. The resistor has a reactance-free character because of which no extra phase displacement is caused.
