Electrical Main Distribution Panel with Auto Inverter changeover supply and Protection against Earth fault, Voltage Variation & Short circuit 30 KW (50 Amp) Load

This Panel will distribute Electrical Power with Protection against Earth fault, Voltage variation, and Short circuit. As a result Electric shock, Electric fire, Damages of components, and Increasing in the Electricity bill amount due to Earth leakage current will be avoided. At the time of failure of Main Electrical supply, The single phase inverter will give supply to three phase connected lighting load. After availability of proper supply, It will change over to main supply.

Specification

Floor mounted Electrical Power distribution Panel fabricated from mild steel sheet dust and vermin proof duly powder coated consists of MCCB, Contactor, Meter, Busbar, Lamps, Auto changeover device for lighting load, Voltage variation and Earth fault protection device, Etc. Outgoing feeders for load distribution will be given as per the customer requirement.

Overall Dimension of Panel 800 (L) x 1800(H) x 300(D) mm (30 KW load)

Working of Protection Device

Voltage Variation Protection

At the time of failure of Main Electrical supply / Voltage variation, supply will be off, Inverter will give supply to lighting load. After receipt of proper voltage, the supply will be changeover to Main supply.

Earth Fault Protection

At the time of Electric shock / Earth fault, Electrical supply will be off with Hooter noise lamp.

Now Press the Reset Push button on panel, so Supply will be on. Hooter noise lamp will be off during the Electric shock / Momentary Earth fault.
Hooter noise lamp will remain in on condition during the existence of Earth fault. Now locate the Earth fault.

If you want to locate the Earth fault after some time, then Put the switch at “Earth fault Protection Bypass” position, so Hooter noise lamp will be off.

To locate the Earth fault, Put the switch at “Earth fault finding” position.
After clearing of Earth fault, Put the switch at “Earth fault Protection working” position,

Short circuit Protection

At the time of Overload/Short circuit, MCCB will trip and Electric supply will be off. After clearing of the fault, MCCB can be made on.

Note – There will not be any breakdown supply problem due to any problem in Voltage variation / Earth fault protection device and Auto changeover device.
