Low Voltage of Electrical Kiosk

Explanation of the low voltage in the electrical Kiosk, which is the third and last component :

After explaining the Ring main unit and the transformer

We now explain the low voltage in the electrical Kiosk :

The left part of the L.V panel:

We find a basic electrical bottom, the so-called (Main Circuit Breaker)
The input to this circuit breaker is the output from the electrical transformer. The value of this circuit breaker is from 360 to 400 volts.

When a so-called trip error occurs, i.e. a malfunction occurs for some reason, the key knife of the electrical breaker drops to the middle, and the maintenance process is carried out after the knife is moved to the sector to shutdown, i.e. to (OFF) and after repair it is turned on (ON).

• 3 current transformers.
• 3 Circuit breaker.
• Copper Bar (Earth Bar) for protection.

• 

Right part of the LV panel:

Consists of :

• 3 amps.
• 1 voltmeter.

We find in the ammeter and voltmeter, each of them has two indicators (red - black).

The red pointer: indicates the maximum value.

The black pointer: expresses the minimum value.

• 

2 -Selector :
Right: It has options (automatic - manual - OFF for the timer)

The left: measures the voltage between two phases (2-Phase) or between Phase and ground (Phase and natural).

• 

2 Circuit Breaker:

Right: for Power Factor

Left: For Timer and its Switch.
