Electrical equipment with rated voltage above how many volts is called high voltage electrical equipment?

According to the definition in the Electric Power Safety Work Regulations (Substation and Power Plant Electrical Part):

1.7 electrical equipment is divided into high voltage and low voltage:

High-voltage electrical equipment: grounding voltage 1000V and above;

Low-voltage electrical equipment: the ground voltage is below1000 v.

1.8 this procedure is applicable to the staff of users' electrical equipment in power generation, transmission, substation, power distribution and use (including infrastructure installation and rural power supply personnel), and other units and relevant personnel refer to it.

Precautions:

The normal operation of electrical equipment is closely related to daily maintenance and inspection. If we can find the problems as early as possible and implement effective measures to solve them, we can not only reduce maintenance time, but also reduce economic losses, improve the economic benefits of enterprises and promote their rapid development.

Regular maintenance of machines is a basic measure to improve the effectiveness of equipment maintenance. Therefore, in daily work, it is necessary to conduct routine inspections on electrical equipment to avoid safety failures.
