For dry-type transformer discharge should be how to deal with it? We still and transformer manufacturers of small make up to understand it in detail:
Power test must use the appropriate voltage level and qualified test appliances, in the maintenance of equipment out of the line on both sides of the power test. Before checking the power should be tested on the electric equipment to prove that the checker is good. High-voltage equipment power test must wear insulated gloves.
Low-voltage circuit outage maintenance should be disconnected from the power supply, remove the fuse. In the knife gate operating handle hang “prohibit closing, someone working” sign.
When working on the capacitor circuit, the capacitors must be discharged one by one. Ground the capacitors after discharging.
When the line or user maintenance requires power outage, the duty officer should take safety measures, and then notify the person in charge of the other party to start work and registration.
