Grounding

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC
FLASH
Failure to properly ground the passive harmonic filter
as per all applicable codes and standards will result in
serious personal injury or death.
To ensure safe operation, the HPS Centurion P
Passive Harmonic Filter must be properly grounded
before energizing. Each filter will come equipped with a
designated main grounding location.

Protection

The HPS Centurion P Passive Harmonic Filter should
be protected by a user supplied circuit breaker or fused
disconnect on the input per electrical code requirements.

Field Wiring

All of the connection points of the HPS Centurion P
Passive Harmonic Filter are clearly marked as follows:
• A1, B1 and C1 should be connected to phases A, B
and C of power supply (branch circuit breaker).
• A2, B2 and C2 should be connected to phases A, B
and C of the load.
Refer to Appendix A for suggested cable entry
locations.

Commissioning/Testing

Field inspection start up and testing shall be
performed by a qualified technician from the owner,
contractor or HPS.
In order to quantify the power quality improvement
due to the HPS Centurion P Passive Harmonic Filter,
measurements can be taken before and after. Before
connecting the Passive Harmonic Filter into the system
you can use a power quality analyzer (e.g. Fluke 1736 or
Hioki 3196) to obtain a baseline for total harmonic voltage
distortion, total harmonic current distortion, power factor,
etc.

input disconnect. Care should be taken that the before
and after measurements are taken at the same speed and
load condition to make a valid comparison. The following
