1. When working on panels that are fully or partially energized, the equipment under maintenance and the equipment in operation should be clearly marked.
2. When performing work with significant vibration such as drilling on protection panels, measures should be taken to prevent the tripping of equipment in operation.
3. All secondary windings of current transformers and voltage transformers should have reliable protective grounding.
4. When working on the secondary circuit of a current transformer in operation, 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 plates and short-circuit wires must be used;
3. It is forbidden to perform any work on the circuit and conductors between the current transformer and the short-circuit terminal;
4. During work, there should be a dedicated person to supervise, use insulated tools, stand on an insulating mat, and the circuit must not be opened.
5. When working on the secondary circuit of a voltage transformer in operation, the following safety measures should be taken:
1. Strictly prevent short circuits 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, dedicated switches and fuses must be installed;
4. When conducting live tests on the secondary circuit, to prevent back-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 the secondary circuit or conducting a withstand voltage test, 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 personnel.
5. Then press the "Close" button for AC operating voltage on the panel
6. Slowly adjust the output adjustment knob to raise the voltage to the required value, and observe the voltmeter.
7. After the test is completed, first press the "Open" button for AC operating voltage on the panel, then press the main "Open" button on the panel. Then, disconnect the main power switch.
