consturction department
In construction department, they responsible to construct substation and overhead pole. Usually, contractor will do the initial work like dig hole for ing, places the switchgear or transformer, place the pole and the other work.
Apart from that, TNB also responsible to shut down the substation that involved in the construction before the contractor start doing their job to avoid accident from happening.
The important work in construction job is ing cable to make sure that the new substation will get the supply to operate . Furthermore ing cable is done when there is breakdown which happened because the cable is damaged.

Breakdown of cable
Low Voltage Overhead Lines
Presently all new lines are constructed using aluminum.
Copper conductors are used only for repair of copper lines.
Advantages of Aluminum :
cheaper than copper
lighter and easier to handle
less scraper value, not prone to theft
Disadvantages of Aluminum :
softer than copper and required careful handling
oxidizes easily making connections more difficult

Poles For LV Overhead Line Four types of poles are used in the TNB :
Wood Poles
Pre-stressed Spun Concrete poles
Reinforced Concrete Poles
The functions of poles are:
To conductors and accessories such as fuses and cable boxes
The safety clearance from the ground, building are maintained
The standard lengths are:
10 meter -
for HT cable (HV)
High Voltage Cable
The 11kV supply that feeds into switchgear comes in the XLPE cable (HV cable).
In one cable, have three cores (R, Y, B) which is connected to the three terminals of incoming feeder of the switchgear.
From the switchgear, the supply goes to the HV side of the transformer through XLPE cable
Switchgear
Transformer
Feeder Pillar
Planning department
This department is responsible to estimation the project include in deg, planning in all new project requested by s and modified system available depends on situation.
This department also responsible to calculate maximum demand, cable size, calculate load, and determine suitable transformer size and switchgear for consumer
Estimating the project
Estimation of substation project involves working out the cost of the following
Land
Salaries
Materials
Contract
Transport
Overhead
SITE VISIT Site visits are essential before planning starts. The following can be obtained from site visits. a) Sources of supply b) Types of loads c) Site information on:
Trees
Ground conditions and terrain
Other services on site such as telephone lines and water mains.
Drains, stream, ponds etc
MAKING A Site visit
Metering unit
Type Of Metering Used To Consumer :
a) Ordinary power consumer meter (OPC meter)
Metering
b) Large Power consumer meter (LPC meter)
Ordinary Power Consumer (OPC)
1. Electromechanical single phase 2. Electronic single phase 3. Electromechanical three phase 4. Electronic three phase
Large Power Consumer (LPC)
1. Electromechanical three phase (LV) 2. Electronic three phase (LV) 3. Electromechanical three phase (HT) 4. Electronic three phase (HT)
Type of metering There are three types of metering 1. Single phases metering (OPC meter).
The current value uses in fuse about 10-50 A.
Use two wire connected from supply to meter board consumer
Having one cut out and one neutral link
2. Three phase metering (OPC meter)
The current value uses in fuse about 10-60 A.
Used four wire connected from supply to meter board consumer
Having one neutral link and three cut out
3. Large power consumer meter (LPC meter).
Use digital electronic meter
Use current transformer
Component of meter a) The devices at meter board are
Cut out
