What happens when the circuit fails?
Generally, when the current is higher than the designed current, the voltage method should not be used for the overhaul, but the power cut is adopted to measure the resistance.
It is better to measure the resistance even if it is necessary. What is said here is general, but only in relative terms.
Because the general current over the high voltage measurement of voltage, especially for a long time, it is extremely easy to expand the fault, and even cause irreparable losses.
