Factory transformer tripped
Thread Content
May I ask, in the event that tests conducted in the factory laboratory cause the factory’s transformer to trip and result in a power outage throughout the factory, if everything is found to be normal, can power be restored on its own or does it require the intervention of the power supply company? Is there any standard for this, and could it violate certain industry laws?
Did your incoming circuit trip, or did it also cause the substation at the power supply company to trip as well? Of course you need to inform them so that service can be restored step by step. There’s no need to bring up laws here; don’t you have any regulations?
If only the transformer in one’s own company fails while the incoming power cabinet remains operational, it is sufficient to communicate with the power supply agency’s dispatch team for power to be restored, as a precaution. If the problem affects the power outlet cabinet at the power supply agency’s end, it is necessary to determine the cause and submit a written request to have power restored. If the failure causes disruptions or complete outages in the power supply to other unrelated businesses, the power supply agency will generally impose penalties
We are currently conducting a risk assessment before the unit tests, taking problems into account in the worst-case scenario. There is a circuit breaker in front of the power supply terminal for the unit; ahead of that circuit breaker lies a backup transformer in the factory along with its own circuit breaker. Now, if the circuit breaker at the lower end of the transformer trips, is it necessary to contact the power supply company?
No experiments have been conducted yet; it’s only a simulation of dangerous situations. If the circuit breaker at the lower end of a backup transformer connected to the factory where the experimental unit is located trips, is it still necessary to communicate with the power supply company in order to restore power supply? Since it involves different departments in the factory, and there is concern that the processing process will be complicated, the factory’s power department refuses to supply electricity. So, it’s better to find out in advance.
Generally, there is no need to contact the power supply company when electrical equipment in a factory trips. It is recommended to conduct tests on the unit with it running under no load, using soft start or variable frequency starting methods, in order to prevent tripping as much as possible
People with an electrician’s license can operate it
The switch at the power supply department did not trip; only the switch inside the factory tripped. Therefore, power was restored step by step in accordance with the factory’s procedures. If one goes directly to the power supply department, it is necessary to determine the cause and submit an application from the household concerned before power can be restored.
