How many samples shall be subjected to the individual type tests according to clause 6.2 of IEC
60831-1 for shunt power capacitors?
Decision
For the performance of a type test on shunt power capacitors according to IEC 60831-1 the following
type test schedule shall be applied:
Type test schedule:
Tests Subclause Number of samples to be inspected
Single-phase
units
Three-phase units
≤ 10 kvar > 10 kvar
Thermal stability test 13 1 1 1
Measurement of the tangent of the loss angle (tan δ)
of the capacitor at elevated temperature
14 1 1 1
Voltage test between terminals 9.2 5 5 3
Voltage test between terminals and container 10.2 5 5 3
Lightning impulse voltage test between terminals and
container
15 5 5 3
Discharge test 16 3 3 3
Ageing test 17 5 3 2
Self-healing test 18 5 3 3
Destruction test 19 5 3 2
