Principle of Repeated Grounding in Distribution Boxes
With repeated grounding, the ground voltage of the leakage device housing can be reduced, and the more the grounding point is repeated, the more effective it is to reduce the neutral-to-ground voltage and the safer the human body. Grounding is a mechanism to protect distribution equipment and people under normal operating conditions, abnormal operational (overcurrent and overvoltage) responses, and hazardous conditions such as shocks. In the low-voltage three-phase four-wire neutral point directly grounded line, the construction unit should. Repeated grounding can be grounded directly from the neutral line or from the housing of the zeroing device. It looks like two lines, and in fact they are all together. Each DISTRIBUTION BOX and controller must be grounded. Any engineer dealing with power supply networks needs to understand the basic.

High-voltage electrical box is divided into secondary distribution boxes
Primary distribution refers to high-voltage systems that transport power over long distances, while secondary distribution involves low-voltage systems delivering power directly to homes and businesses. A feeder usually begins with a feeder breaker at the distribution substation. Many feeders leave substation in a concrete ducts and are routed to a nearby pole. Primary Distribution: Involves the transmission of high. The electricity supply chain consists of three primary segments: generation, where electricity is produced; transmission, which moves power over long distances via high-voltage power lines; and distribution, which moves power over shorter distances to end users (homes, businesses, industrial sites. Each part can be subdivided into two systems: primary transmission and secondary transmission and similarly, primary distribution and secondary distribution and lastly the individual supply system to the individual consumers. More often than not, generation and transmission is solely three-phase.
