The case Main Circuit Breaker in position. The Trip. electricity., pig, more than size. Amp.Trip (AT) of Circuit Breaker., electricity, short circuit (Short Circuit) in the electrical system. was born Ground Fault (electricity, short circuit to ground), which has caused the very frequently, about 75%.The problem of electricity, defects caused ขึ้นทั.All.. Due has been installed.The Phase Protection Relay to prevent two scan. Main Circuit Breaker.By observation, the Trip discs. Under Voltage Relay which is in Main Circuit Breaker which.The case will cause Trip is as follows. electrical voltage, incomplete phase. pressure electricity showers (Under Voltage Relay can be adjusted 5-20% of normal pressure). electricity voltage exceeding the 15% of normal pressure (Over Voltage Relay can be adjusted 5 -.20% of normal pressure). pressure electricity from the electricity level.
