In the power system, it is crucial to ensure user safety when the power submeter is used in a high voltage or China Electrical Cabinet Dehumidifier  high current environment. Here are some key measures to ensure user safety in a high voltage or high current environment:

Choose a suitable power submeter:
Choose a power submeter that meets national standards and industry specifications according to the voltage and current levels in the actual use scenario.
Ensure that the power submeter has high reliability, high accuracy and strong anti-interference capabilities.
Implement insulation protection measures:
Insulation materials are the key to preventing current leakage. Ensure that the insulation layer of the power submeter is intact and the thickness meets the requirements.
For personnel who directly operate the power submeter, personal protective equipment such as insulating gloves and insulating boots should be equipped to reduce the risk of electric shock.
Set up physical barriers and warning signs:
Set up physical barriers around high voltage or high current equipment, such as fences, isolation boards, etc., to prevent non-professionals from approaching.
Set up warning signs in obvious locations, clearly mark the voltage level, safety distance and precautions, and remind personnel to pay attention to safety.
Strengthen safety training and awareness:
Regularly conduct safety training for users of power sub-meters to improve their awareness of safe operation in high voltage or high current environments.
Through brochures, safety meetings and other forms, popularize power safety knowledge and enhance users' safety awareness.
Implement regular maintenance and overhaul:
Regularly maintain and overhaul power sub-meters to ensure that they are in good working condition.
Check the insulation layer, wiring terminals and other key parts of the power sub-meter to promptly discover and deal with potential safety hazards.
Strengthen safety inspections and coordination and communication:
Strengthen communication and coordination with users, understand users' electricity demand and equipment usage, and promptly feedback and deal with safety issues.
Regularly conduct safety inspections on power sub-meters to ensure safe and stable operation of equipment.
Establish an emergency response mechanism:
Develop an emergency plan for power safety accidents, clarify the emergency response process and division of responsibilities.
Organize emergency drills regularly to improve the ability to respond to power safety accidents.
By taking the above measures, the safety of power sub-meter users can be effectively ensured in high voltage or high current environments.
