LV Active Filters PQF
Commissioning report
8.11.2 Inspection on site – verification of the active filter after installation
Ambient conditions
–
Check the ambient temperature (< 40°C/104°F) (if > 40°C/104°F, derating is required)
–
Check the installation altitude (< 1000m/3300ft) (if > 1000m/3300ft, derating is required)
–
Check the ventilation (room and enclosure)
–
Ensure that no sources of conductive dust are present
Upstream cabling and protection
–
Upstream protection installed
–
Check cross-section of power supply cables (L1-L2-L3) and neutral (if connected)
–
Check cross-section of protective conductors (PE) (/ 16 mm²) connected to each
enclosure.
–
Check the setting and operation of the protective apparatus
–
PQFS neutral current can be up to 3 times the PQFS phase current!
–
Check rated current of the power supply cable fuses (if applicable)
–
Check tightness of conductor fixations
–
The material of busbars, terminals and conductors must be compatible (corrosion)
(a)
Internal connections
–
Disconnect the filter from the supply (disconnection recommended by upstream protection)
–
If filter connected to the supply before, wait 25 minutes to discharge DC capacitors
–
Remove the filter protective cover, disconnect PQF-Manager if required
–
Open auxiliary circuit fuse protection box
–
DC capacitor voltage low enough to operate safely (DC voltage measurement)
–
Filter hardware configured for the desired network voltage (208-240 V or 380-415 V)
–
Wiring of main and auxiliary circuit
–
Tightness of all electrical connections
–
Connectors properly plugged in
–
Fixation of components
–
DC capacitor voltage low enough to operate safely (DC voltage measurement)
–
Remove anti-corrosion capsules installed at the inside bottom of the filter (if still present)
–
Clearances
–
Address of each filter unit in a multi-unit system set to a different value and 'main' master
has the lowest address
–
CAN bus terminated properly on each unit of a multi-unit system
–
CAN bus communication cable between the different units properly installed
(a)
Installation
–
Check the cabling of the digital I/O (if present)
–
Check the voltage in accordance with the specification
–
Check the phase rotation order (with filter auxiliaries off) (clockwise)
–
For multi-unit filters, check that the same phases are connected to the same filter power
terminals for the individual units
–
Check visually the current transformers
