(1) The secondary side of a non-current transformer must remain open during operation, except for low-current transformers. This is crucial to prevent damage to the equipment and ensure safe operation.
(2) When working with current transformers, the secondary winding must be short-circuited using appropriate shorting devices. It is strictly prohibited to use wires or any other makeshift methods to create a short circuit, as this can lead to dangerous voltage spikes and potential equipment failure.
(3) Any work performed on the circuits or wiring between the current transformer and the short-circuit terminal requires strict safety precautions. A detailed secondary work safety measure must be completed and followed to ensure the protection of both personnel and equipment.
(4) During any maintenance or testing activities, it is essential not to disconnect the permanent grounding point of the circuit. This grounding provides a critical safety path for fault currents and helps prevent electrical shocks.
(5) All work involving current transformers should be carried out under the supervision of a qualified guardian. Personnel must use insulated tools and stand on an insulating mat to minimize the risk of electric shock and ensure a safe working environment.
These safety measures are essential to maintain the integrity of the electrical system and protect workers from potential hazards. Always follow established procedures and guidelines when handling current transformers.
