Discharge the capacitor - single phase
01. Discharge reactor (5-10kOhm)
02. Multimeter
03. Capacitor
Discharge the capacitor - three phase
01. Discharge reactor (5-10kOhm)
02. Multimeter
03. Capacitor
At three phase capacitors the discharge must be made
between every phase (L1-L2; L2-L3; L1-L3)
Checking
Switch the multimeter to capacitor measuring and connect
the meter end probes to the capacitor terminals. Measure
capacity of the capacitor.

Fig. 6.11.2-3: Capacitor checking
Check all capacitors in the electrical cabinet
Test each capacitor by touching the multimeter (set on capacitor measuring) probes on the capacitor terminals:
measure the capacity of the capacitors.
The capacitors should not be removed from the electrical cabinet before the check is made.
Checking the electrical connections to the Capacitor
It must be ensured that the electrical connections to the capacitor are always tight fitting. Loose connections with
transitional resistance can mean that the contact surfaces will become heated externally. This can lead to faster
deterioration of the capacitors.
