WHERE TO SET UP THE PRIMARY SURGE PROTECTOR

Primary distribution box surge protector

The distribution box surge protector acts as your home's central nervous system guardian. Surge protectors (Surge Protective Devices, SPD) installed in distribution board panels are primarily used to protect electrical equipment from transient voltages (surges or spikes) caused by lightning strikes, power grid fluctuations, or other factors. The first-level SPD, with a test waveform of 10/350μs, mainly protects against direct lightning strikes, and has the characteristics of large flow rate and strong discharge.

Set up a primary power distribution box

Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers.

Where should the primary power distribution box be connected during construction

The main distribution box shall be located in the area close to the power supply; the distribution box shall be installed in the area with relatively concentrated electrical equipment or load; the distance between the distribution box and the switch box shall not exceed.

It has three categories: residential, commercial and industrial electrical distribution boxes, all of which play important roles in their respective electrical.

Where should the relay protection be set

Relay coordination refers to setting protective devices so that the relay closest to the fault operates first, while upstream relays act as backups. Also principles of various protective relays and schemes including special protection. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. Combines protection, sensors, control power, and circuit breaker in a single package Typically added to a breaker close circuit to prevent accidental reclosure after a trip.
