voltage detectors
The voltage presence/absence detector installed in
cpg
.0
lite cubicles is designed and built in accordance with the
recommendations laid down in Standards IEC 61243-5,
VDE 0682 Part 415, within the built-in detectors without
auxiliary power supply category.
The unit has three light signals corresponding to phases
L1, L2 and L3. On the front of the indicator, a test point is
accessible for each of the phases and earth, which is used
to test the balance of all phases. We recommend use of any
universal phase comparator which complies with Standard
IEC 61243-5. As an option, the detection unit has a free
auxiliary contact for remote indication of voltage presence/
absence.
The device indication complies with the requirements laid
down in Standard IEC 61243-5:
• No voltage: U(*) < 10 % U
n
(**)
• Uncertainty: 10 % U
n
< U < 45 % U
n
• Voltage presence: U > 45 % U
n
(*) U = phase-to-earth voltage.
(**) U
n
= rated operating voltage.
The presence of voltage is indicated by activation of the
LEDs for each of the phases. If the presence of voltage is not
detected, the LEDs for each of the phases remain unlit.
8.2. Locking with padlock
Optionally, on request, the cubicles are supplied with
independent padlock interlocking for both the feeder
disconnector in its open or closed positions, and the
earthing switch in open or closed positions. Padlocks with 8
mm shackle diameters can be used.
Circuit-breaker operation buttons can be locked individually
using a padlock with an 8 mm-diameter shackle.
8.2.1. Locking with key lock
Both the feeder disconnector and the earthing switches can
have an optional key locking device, which allows operation
to be blocked in both open and closed positions.
