对于测试仪器是有功率要求的。如电压与电流的积哟!100毫安电流，3750伏特电压，功率就是375瓦特啦!作者: xshrmm 时间: 2011-11-20 02:26

那家电里有
The high-voltage source used for the test is to be capable of supplying a short circuit current
Is between the output terminals after the output voltage has been adjusted to the appropriate
test voltage. The overload release of the circuit is not to be operated by any current below the
tripping current Ir. The values of Is and Ir are given in Table 5 for various high-voltage
sources."
