It is measured one by one with multimeter and filters out two required terminals, the spent time is longer, usually ten minutes or so.2）Terminal
Not only quantity is more, but also arranges than comparatively dense, when test the frequency it is more when, it is understood that there may be accidentally touch terminal, so as to cause certain two
A terminal short circuit is made to cause protective relaying maloperation, to cause the security risks such as power network safety operation.3）For carrying
Take the work of PT secondary side voltage signals, the insufficient young employee of working experience, it usually needs the ability under the guidance of old employee
Smoothly carry out, virtually also occupies certain manpower.
