3 - Components of PCC- Power Command Control Panel:

1- Metering Section

Measuring meters are used for measuring the system parameters like as volt meter, amp meter, multifunction meter etc.

A- Measuring meters

Many types meters are used in panel like as Analog meter and digital meters. Amp meter, volt meter, multi function meter, energy meter are used for measuring the parameters. It all can be used digital or Analog as per requirement.

B- Indicators

Indicators are used for knowing the status of panel operation.Difference type indicators are used with different color.

• R Phase.
• Y Phase.
• B Phase.
• Breaker ON.
• Breaker OFF.
• Breaker Trip.

C- Selector Switches

• Amp selector switch
• Voltage selector switch
• TNC switch

2- Supply incomer Section:

Two nos supply source incomer are available and connected with busbar. If one supply source is problem then other source can be connected with the help of buscuppler.
Air circuit breaker are used for making and breaking supply.

3- Outgoing feeder section:

Outgoing feeder are used for distributing power supply like as high riser tower-1 a side, tower-2 b side etc. Air circuit breaker are used for making and breaking supply in outgoing feeders.

4- Bus Coupler Section:

Bus coupler are used for eliminating incomer sources each other. If one source is not working then other source can be connected with the help of buscuppler.
