MiCOM P543, P544, P545 & P546
CM
4. EQUIPMENT REQUIRED FOR COMMISSIONING
4.1 Minimum equipment required
Multifunctional dynamic current and voltage injection test set.
Multimeter with suitable ac current range, and ac and dc voltage ranges of 0 - 440 V and
0 - 250 V respectively.
Continuity tester (if not included in multimeter).
Phase angle meter.
Phase rotation meter.
Note: Modern test equipment may contain many of the above features in
one unit.
Fiber optic power meter.
Fiber optic test leads (type and number according to application).
P594 Commissioning Instructions. If the scheme features P594 time synchronizing devices,
these will need commissioning. Separate documentation containing commissioning
instructions is available for the P594.
4.2 Optional equipment
Multi-finge
r test plug type P992 (if test block type P991 installed) or MMLB (if using MMLG
blocks).
An electronic or brushless insulation tester with a dc output not exceeding 500 V (for
insulation resistance testing when required).
A portable PC, with appropriate software (this enables the rear communications port to be
tested, if this is to be used, and will also save considerable time during commissioning).
KITZ K-Bus to EIA(RS)232 protocol converter (if EIA(RS)485 K-Bus port is being tested and
one is not already installed).
EIA(RS)485 to EIA(RS)232 converter (if EIA(RS)485 MODBUS port is being tested).
A printer (for printing a setting record from the portable PC).
