8.11.2 Inspection on site – verification of the active filter after installation
Ambient conditions
OK/NOK
– 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
Intern
al connections
(a)
– Disconnect the filter from the supply including the auxiliary circuit (disconnection recommended
by upstream protection)
– Remove filter internal protection grid
– DC capacitor voltage low enough to operate safely (DC voltage measurement)
– Change auxiliary transformer primary tap setting to correspond to network nominal voltage
rating
(b)
– Wiring of main and auxiliary circuit
– Tightness of all electrical connections
– Connectors properly plugged in
– Fixation of components
– Remove anti-corrosion capsules installed at the inside of the filter door (if still present)
– Clearances
– Cooling fans running freely
– Address of each filter unit in a multi-unit system set to a different value and ‘main’ master has
the lowest address
(c)
– CAN bus terminated properly on each unit of a multi-unit system
(c)
– CAN bus communication cable between the different units properly installed
(c)
– Earth interconnection between the different units installed
Installation
(a)
– Check cross-sections of power supply cables (L1-L2-L3)
– Check cross-section of protective conductors (PE) (> = 16 mm²) connected to each cubicle and
between cubicles.
– Check tightness of conductor fixations
– The material of busbars, terminals and conductors must be compatible (corrosion)
– Check the setting and operation of the protective apparatus
– Check rated current of the power supply cable fuses (if applicable)
– Check the cabling of the digital I/O (if present)
– Check the voltage in accordance with the specification
– Check the phase rotation order at the filter power terminals (with filter auxiliaries off)
(clockwise)
( b)
– 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
- Ratio
- Installed at the right side (feeding-side of the active filter)
– For multi-unit filters, check that the CTs of all units are cabled in a daisy chain fashion with return
path
( d)
– Remove all jumpers of all current transformers (CTs and SCTs)
