High Voltage Switch Energization Test Device - Production PriceSafety Technical Operation Regulations:
1. When working on panels that are fully or partially energized, the equipment under maintenance should be clearly marked to distinguish it from operating equipment. [1]
2. When performing work with significant vibration, such as drilling on protection panels, measures should be taken to prevent the operating equipment from tripping.
3. The secondary windings of all current transformers and voltage transformers should have reliable protective grounding.
4. When working on the secondary circuit of a running current transformer, the following safety measures should be taken:
1. It is strictly forbidden to open the current circuit;
2. To reliably short-circuit the secondary winding of the current transformer, short-circuit pieces and short-circuit wires must be used;
3. It is forbidden to perform any work on the circuit and wires between the current transformer and the short-circuit terminal;
4. During work, a dedicated person should supervise, use insulated tools, stand on an insulating mat, and must not disconnect the protective grounding in the circuit.
5. When working on the secondary circuit of a running voltage transformer, the following safety measures should be taken:
1. Strictly prevent short circuit or grounding;
2. Insulated tools should be used, and insulating gloves should be worn. If necessary, the relevant relay protection devices should be deactivated before work;
3. When connecting temporary loads, special switches and fuses must be installed;
4. When conducting energization tests on the secondary circuit, to prevent reverse transformation from the secondary side to the primary side, in addition to disconnecting the secondary circuit, the primary fuse should also be removed;
5. Before energizing or conducting withstand voltage tests on the secondary circuit, the duty personnel and relevant personnel should be notified, and someone should be assigned to guard the site, check the circuit, and confirm that no one is working before applying voltage.
6. Personnel inspecting the trip protection and secondary circuits are not allowed to perform any switching operations without the permission of the duty officer.
