1. TYPICAL ELECTRICAL DISTRIBUTION SYSTEM IN
PALM OIL MILLS1.1 LAYOUT OF POWER GENERATORS, MAIN SWITCHBOARD, MOTOR CONTROL PANELS AND POWER CABLES Power Supply System In Palm Oil Mill
BAY Different Parts of Power System (a)
Generating Sets Comprising Steam, Diesel and Gas Types (Sinar Mas is considering installing Biogas Engine)
(b) Main Cables
Linking Generating Sets and Main Switchboard. Commonly used are PVC/PVC Single Core Copper Conductors. Due to flexibility. (c)
Main Switchboard Comprising Generator Control Boards, Outgoing Distribution Panels, Switching Panels and Capacitor Boards.
(d) Sub-Main Cables
Linking Main Switchboards and Sub-Switchboards. Commonly used are 4 Core Armoured Cable or 4 Core Paper Insulated Lead Alloy Sheathed Cable. (e)
Sub-Switchboard Another name is Motor Control Panel. Starter Boards are located here.
(f) Loads Comprising Electric Motor, Lighting, Heating, Air-Conditioner, Equipment.
1.2 MAIN SWITCHBOARD
1.2.1 MAIN SWITCHBOARD
These are attachment of panels to control power intake from generators and power flow to load centres under control conditions. The operations are executed by the use of ACB, MCCB, Protection Equipment, Metering Equipment, Selector Switches, Change-over Switches, P.F. Capacitor Banks, Bus-bars, Cables, etc. The Main Switchboard comprises : (a)
Generator Control Panel
(b) Loads Control Panel
(c) Change-over Panel
(d) Automatic Power Factor Correction Panel
(e) Synchronising Panel
These panels are fabricated from 10 SWG and 12 SWG Sheet Metals for Frame Work and Door/Covers respectively. These sheet metals are first cleansed throughtly, given a phosphate treatment before being painted with two undercoats of zinc chromate. The panels are then painted with two l ayers of enamel orange on the outside and two layers of ‘white’ on the inside.
1.2.2 GENERATOR CONTROL PANEL

1.2.3 LOADS CONTROL PANEL
Power flow from these panels are control by : (a)
Moulded Case Circuit Breaker (MCCB) (b)
No Fuse Breaker (NFB) (c)
Fuse Switch (F/S) (d)
Switch Fuse (S/F) (e)
Socket Outlet The advantages of MCCB or NFS over F/S and S/F are : (a)
No change of fuse is necessary (b)
Re-set when trigger by overload (c)
Small and compact (d)
Large ratings can be manufactured Standard Ratings of TPN MCCB are : (a)
30 A
Overloads are fixed (b)
60 A
(c) 100 A (d) 225 A (e) 400 A (f) 600 A
Overloads can be adjusted (g) 800 A
(h) 1000 A (i) 1250 A
Power Fuse (to protect capacitor bank)
6-steps Regulator provide switching up to 6 capacitor banks. 12-step Regulator provide switching up to 12 capacitor banks. (c)
(b) Electronic Power Factor Regulator is normally available in steps of 6 and 12.
Indicating Lights (to show no. of steps being switched on)
Ammeter (measure amperes)
Measurement Current Transformer (to sense reactive power)
Electronic Power Factor Regulator (P.F. Controller)
AC Contractor (to provide switching of capacitor Bank)
1.2.4 CHANGE-OVER PANEL
Main Switch (to protect system)
(a) This comprises :
1.2.5 AUTOMATIC POWER FACTOR CORRECTION PANEL
(d) The advantage of this type of design is FLEXIBILITY IN OPERATIONS. (e) At timers KEY INTERLOCK is provided to prevent mal-operation.
The purpose is to tap power supply from ‘Steam Bus-Bars’ OR ‘Diesel Bus- Bars’.
This is done by the use of 4 Pole Change-Over Switch and Main Switch (ACB, MCCB, F/S). (c)
(a) This can also be called Switching Panel. (b)
Measurement Current Transformer should be installed at location where the total power demand flows through. This is to ensure total correction of all inductive reactive load. (d)
The time response setting of Power Factor Regulator = (e)
Example : System has 6 x 65 KVAr Capacitor Banks Measurement Current Transformer use 2000/5A.
Thus Time Response Setting = = = = 0.1625
65 2000 / 5 65 x 5 2000

KVAR CT ratio
1.2.6 SYNCHRONISING PANEL
Selector Switch (to select gen-set to be paralleled)
Synchronising Light (indicate phase sequence)
Double Frequency (indicate bus-bar and incoming set frequency)
(b) Synchronising Panel is require to assist in paralleling of generating sets.
(c) Paralleling is done at the instance of :
Equality is voltage
Equality in frequency
Equality in phase sequence
Double Voltmeter (indicate bus-bar and incoming set voltage)
Synchronoscope (indicate phase sequence)
(a) This consists of :
Instrument Fuse (to protect meter and equipment)
(d) Paralleling of generating sets than the above conditions can cause serious damage to generators, switchgears and meters due to large circulating current.
