RS DISTRIBUTION BOARDS
A Distribution board is a component of an electricity supply system which divides an electrical power feed into subsidiary circuits , while providing a protective circuits breakers for each circuit , in a common enclosure . They receive their feed from SMDB.
LOW VOLTAGE AC SYSTEM (SIEMENS) PANEL
The LVAC (SIEMENS) panel made according to the technical specification of (MINISTRY OF ELECTRICITY) MOE in 2012 for substation 33/11 KVA (2×31.5MVA) and IEC standard
the supply will be taken from the 11/0.416kV Aux. transformer. Arrangement and connection details of the AC
The LV AC switchboard is free standing metal clad totally clad enclosed Indoor type
Designed for 400/230V, 3-phase, 4-wire, 50Hz with solidly earthed neutral and bus-bar rating of 500A.
The switchboard comply with IEC 60947 and IEC 60439.
The incoming of the main 400/230V distribution circuit supplied through a 4-pole Molded Case Circuit Breaker (MCCB) of nominal current rating 400A.
The protection to be provided by thermal and magnetic release for over load and short circuit trip with time lag and compensation for ambient temperature
The adjustment of the over load protection between 80 to 120% of the full load rating.
The incoming circuit provided with voltage meter & ampere meter, AC under-voltage relay, phase-sequence relay, earth fault sensing relay and the respective alarm indication.
The rated symmetrical breaking capacity 35kA
The outgoing feeders from the main distribution circuit individually controlled and protected by means of MCCB rated at the pertaining circuit loads.
The nominal rating of each unit 20A.
The outgoing circuits breakers are molded case circuit breaker varied size 100A, 63A, 32A
