Introduction to Testing and

Commissioning of Power
System

3.1 INTRODUCTION
The term “commissioning” refers to a start-up test of the electrical equip-
ment that is undertaken before the initial energization of the equipment.

3.1.1 Precommissioning Procedures

Before commencing a commissioning test, some steps must first be undertaken:
Approved design drawing should be on site ready to start the work.
Review all wires in the marshaling kiosk, control panels, protection
panels, and low voltage switch boards. After review these wires should
be highlighted by yellow marker in the schematic drawings.
During the wiring review, the tightness of all terminal blocks needs to be
confirmed. Low voltage panel bolts tightness torque needs to be
reviewed, usually tested at 70 Nm.
A panel wires review should be undertaken at local control cubicles (LCC)
and inprotectionpanelsinthe control room. The review should also include
transformer boxes, low voltage motor control center, and similar items.

3.1.2 Commissioning Management
A commissioning team consists of the commissioning manager and commis-
sioning engineers. The responsibilities of the commissioning manager
responsibility are:

1. Producing the commissioning program.
2. Follow up of the commissioning team.
3. Coordinate with other stakeholders on the project regarding commissioning.
4. Ensure that the project has the required resources to perform the different
tests required and all material, facilities, tools are on site.
