The high impedance of the secondary circuit in a voltage transformer plays a crucial role in determining the safety procedures that must be followed when working on it. One of the key concerns is to prevent any short circuits or grounding in the secondary circuit, as these can lead to serious equipment damage or even electrical hazards. To ensure safe operations, the following guidelines must be strictly adhered to.

(1) When performing wiring work on the voltage circuit, it is essential to wear insulated gloves and use insulated tools. All operating plates should be stable and accurately positioned, and all knobs must be securely tightened at each setting. Any broken wires on terminal blocks should be clearly marked, insulated, and properly secured to avoid accidental contact or shorting.

(2) For temporary test loads connected to the secondary power supply line, a fuse with appropriate rating should be used. The fuse current must match the protection characteristics of the voltage transformer’s fuses. In case of a ground short circuit in the load section, the fuse at this stage should blow first, preventing the main circuit fuse from being affected and ensuring system stability.

(3) If disconnecting leads from certain secondary equipment could potentially cause protective components to malfunction, it is necessary to notify the dispatching department or production supervisor. Appropriate measures should be taken, and if required, the affected components should be temporarily removed from operation to prevent unnecessary tripping or system instability.

By following these safety protocols, technicians can significantly reduce the risk of electrical faults and maintain the integrity of the voltage transformer system during maintenance and testing activities.
