1.3.1

The safety knowledge in operation
Before the start of any testing it should be confirmed that all power supplies to the system have
been isolated or that they are in a known condition. The Commissioning engineer is
responsible for the safety of those personnel working of the system Check for the presence of
harmful electrical or mechanical potential energy before starting work.

1.3.2

Project Lockout / Tag out (LOTO) procedures must be adhere to all test area.

1.3.3

Fire is strictly prohibited on site, no smoking there must be a warning mark in hazardous area.

1.3.4

Strictly comply with the safety and environmental protection regulations of local government.

1.3.5

In order to ensure the reliable operation of every part of the system, strictly obey the
corresponding procedures.

1.3.6
1.3.7

Have a regular maintenance for the long-time standby equipment
Obey the relevant safety regulations of the power plant during commissioning all along. Ensure
the successful commissioning work.

1.3.8

All personnel directly involved with the commissioning that will attend a kickoff safety meeting to
review for the dangers. Ensure that all personnel understand the process and the operation.
Any personnel involved in the commissioning have the authority to terminate the operation at
any time, if a serious problem or safety issue develops.

2.2

Protection Relay & Tariff Meter
Protection relay and tariff meter are fully numerical in their design, implementing all protection
and non-protection functions in software. The equipment employ a high degree of selfchecking and, in the unlikely event of a failure, will give an alarm. To commission equipment,
it is only necessary to verify that the hardware is functioning correctly and the applicationspecific software setting have been applied to the equipment. It is considered unnecessary to
test every function of the equipment if the settings have been verified by one of following
methods;

2.3

-

Extracting the settings applied to the relay using appropriate setting software

-

Via the operator interface

Setting
The equipment will be tested in accordance with the application-specific settings furnished by
the contractor, after which, tests should be made to determine if the actual operating
characteristics check with the adjustments made.

2.4

Testing Equipment Required
-

OMICRON CMC256+ test sets (Secondary Injection Tester).

-

An insulation tester and multi-meter

-

A laptop PC with setup software,

-

Multi-finger test Plug
