Supermarket electrical equipment management

Therefore, the regional power supply department is generally required to provide two 10KV power supplies as the main power supply. Two transformers and low-voltage contacts are set in the substation. On this basis, diesel generators can be added as the standby power supply according to the owner's requirements. Diesel generator capacity includes refrigeration equipment, weak current equipment, important processing equipment in fresh food processing area, and equipment used in supermarket logistics system.
