Commissioning and maintenance of the fault clearing

system

About this chapter

This chapter discusses maintenance tests and other periodic maintenance measures.

7.1.1

Commissioning tests

During commissioning all protection functions shall be verified with the setting values
used at each plant. The commissioning tests must include verification of all circuits by
highlighting the circuit diagrams and the configuration diagrams for the used functions.

Further, the settings for protection functions are tested and recorded carefully as
outlined for the future periodic maintenance tests.

The final testing includes primary verification of all directional functions where load
currents is checked on the local HMI and in PCM600. The magnitudes and angles of
all currents and voltages should be checked and the symmetry verified.

Directional functions have information about the measured direction and, for example,
measured impedance. These values must be checked and verified as correct with the
export or import of power available.

Finally, final trip tests must be performed. This involves activation of protection
functions or tripping outputs with the circuit breaker closed and the tripping of the
breaker verified. When several breakers are involved, each breaker must be checked
individually and it must be verified that the other involved breakers are not tripped at
the same time.

7.1.2

Periodic maintenance tests

The periodicity of all tests depends on several factors, for example the importance of
the installation, environmental conditions, simple or complex equipment, static or
electromechanical IEDs, and so on.
