Electrical high voltage equipment refers to devices and systems used for the generation, transmission, and distribution of electricity at high voltages, typically above 69 kV. This includes equipment such as transformers, circuit breakers, switches, insulators, and surge arrestors.

High voltage equipment is crucial for ensuring efficient and reliable power supply to industries, commercial establishments, and homes. However, it also poses a significant risk to safety and requires specialized training and precautions to operate and maintain safely.
