1.0 OBJECTIVE
To provide instructions for electrical testing of Protection Equipments before putting
into service. It included visual inspection of the Protection Cubicle’s for proper
installation and cleanness, to verify the correct operation and to verify equipments meet
the acceptable requirements.
2.0 ACCEPTANCE CRITERIA
This procedure applies to the following testing for Protection System.
1) Visual Check of Protection Equipments
2) Protection Cubicle Mechanical and Electrical Functional Tests
3.0 PROCEDURE
3.1 VISUAL CHECK
The system is checked with mentioned items below visually.
3.1.1 Missing Equipment
The devices and equipments that are shown on the drawings are checked to be
mounted
3.1.2 Cable Connections
Power and control cable connections are checked according to drawings
3.1.3 Earthing of Panel
Panel should be earthed from the earthing busbar or earthing terminal
3.2 CUBICLE ELECTRICAL AND MECHANICAL FUNCTIONAL TEST
The systems is functionally tested with mentioned items below as electrical and mechanical.

3.2.1 Mechanical Checks of Cubicle
The panels are checked that its door and moving parts are operating well
3.2.2 Polarity of DC Voltage
Before energising the system, firstly the terminal connections are checked. After
supplying DC voltage to relevant system, it should be sure that the polarity is
correct by measuring on L(+) and L(-) terminals.
3.2.3 Internal Functional Test
Internal circuitry of panel is checked to be working, regarding the drawings.
3.2.4 External Functional Test
Signals between panels, CB Commands and other equipments of the system isverified according to drawings.
3.2.5 Relay Software Download and Interlocking Conditions
Prepared relay settings file is downloaded to device. Inputs and Outputs are
checked by connection to relay. Interlocks over the relay (CFC etc.) are checked,
regarding the drawings.
3.2.6 Secondary Voltage-Current Injection
All measurements of current and voltage circuits are observed with secondaryinjection.
3.2.7 Simulation of Protection Functions
Protection relays are tested for trip limits by simulation of fault conditions. Trip
signals are also observed. (Omicron156/256 or eqv. is used.)
