When the power is greater than the working value of the regulator. If a leakage protection system is installed, it will trip when the leakage occurs. The voltage is lower than the voltage adaption range of the voltage stabilizer, and the voltage stabilizer can no longer work normally.
If it does not trip at ordinary times but it trips or trips easily when using a certain electrical appliance, it means that the electrical appliance has leakage or poor insulation. If only a certain line is used, that is, a certain line jumps as soon as the power supply is supplied, it means that there is a place for leakage of this line.
220V voltage stabilizer
If an electrical appliance does not jump at the beginning when it is in use, but it jumps after a while, it means that the insulation of the appliance is aging(three-phase voltage regulator), thermal stability has deteriorated, and leakage occurs.
If it trips when using electrical appliances with relatively large power consumption or when there are more electrical equipment in use at home, it means that the air switch of your home (home PVC air switch or leakage protector) is tripped. If the rated current is smaller, you should replace it with a suitable leakage protector with a larger rated current.
If no load will trip, try using a multimeter to check whether the output voltage of the regulator is abnormal before tripping. If it is normal, the protection circuit may fail or a certain control relay transistor may be damaged. If the output voltage is not correct, it may control the voltage regulation circuit. The fault protection automatically cuts off the power, and the working principles of various voltage stabilizers are different. It is recommended to send for repair after removing the cause of the load short circuit.
Change to a suitable leakage protector with a larger rated current. Replace with a larger total brake capacity; replace an air switch, replace a relatively larger cable; replace a high-precision voltage stabilizing equipment; when purchasing a voltage stabilizer, choose a product with safety and quality assurance.
Here, I recommend the voltage stabilizers produced by SCIENTEK ELECTRICAL manufacturers, both in terms of quality, technology, and service.
