Abstract
PURPOSE: To obtain possibility for carrying out tests in automatically measuring correct performance value without getting any affection from redidual magnetism by detecting performance value of device to be tested by means of semi-fine adjustment and secondary, after once intercept its current, detect performance value by fine-adjustment.
CONSTITUTION: For test sample 1 of protective relay, supplied test electric current in each level L21...L24, L23, L25...L27, controlled by computer 3, from electric source instrument 2. At testing stage set initial value of current to be applied for sample device, for example, in 90% of appointed value performance value and make test, and then change it in next stage for example, increase current 5 count in each as semi-fine adjustment value, and at the time sample instrument come into action, cut current once and let rest sample instrument 1. Then again supply less value current than performance value with which sample instrument 1 come into action, for example, 5 count less for sample instrument 1 and after that, by setting value in fine adjustment value, for example increase current 1 count in each, can get correct performance value, escaping from affection from residual magnetism.
