COMMISSIONING AND CALIBRATION
Prior to being put into service, the electrical protection system must be correctly commissioned. This
manual does not cover system commissioning; the full scope of commissioning tests should be
determined during the risk assessment or FMEA covering the design of the electrical protection system.
The following test can provide guidance on checking the correct operation of the IPD during
commissioning. This is not intended to provide an exhaustive commissioning checklist, but should be
considered to be a minimum set of tests.
6.1 Fan Interlock
Ensure that systems employing fan interlock circuits do not allow outlets to energise until the interlocked
fan outlet is running correctly.
6.2 Earth Leakage
Test the correct operation of earth leakage circuits by injecting a fault current through the toroid. Ensure
that all relevant tripping circuits operate successfully and that latched trips may be reset in the
appropriate manner.
Disconnect the toroid from the IPD and ensure that a toroid fault trip is issued with similar effect.
6.3 Earth Fault Lockout
Test the correct operation of Earth Fault Lockout protection by connecting test resistors on the relay side
of the CCMD, per
. With these resistors in circuit, the outlet should be prevented from
energising.
6.4 Earth Continuity
Test that the Earth Continuity protection is operational by creating an open circuit on the pilot wire.
Ensure that all relevant tripping circuits operate successfully and that latched trips may be reset in the
appropriate manner.
Repeat with a short circuit between the pilot and earth.
6.5 Insulation test
If the Earth Fault Lockout and Earth Continuity tests are successful, ensure that a manual insulation test
can be successfully conducted via the IPD.
Also check that an automatic insulation test is initiated by the IPD when a START signal is generated.
6.6 Over Current / Motor Overload Current Injection
Test the Over Current / Motor Overload protection by carrying out secondary injection on the CT
terminals of the IPD.
Where Over Current (IEC 60255-151) protection is employed, inject 2x FLC into one of the CT terminals
and ensure that all relevant tripping circuits operate successfully, in the time expected according to the
settings employed, and that latched trips may be reset in the appropriate manner. Repeat on the second
set of CT terminals.
If Motor Overload that all relevant tripping circuits operate successfully, in the time expected according to
the settings employed, and that latched trips may be reset in the appropriate manner.
