OUBLE EARTH TESTER
BSG1000,
CODE
PII21166
.
The BSG1000 is an external module, that allows measuring the main contacts timing even if both
ends of the CB are connected to ground, for enhanced safety. The option solves also the problems
of wrong detections when the connection cables are subject to a rather high induced current.
Besides, if the Circuit Breakers has a graphite nozzle, CBA2000 displays the timing at which the
graphite is engaged, and when the main contact is reached, thus allowing to check the deterioration
of the graphite.
The options do not allow to detect the pre-insertion resistance, as it is shunted by the ground
connections.
Available options:
- BSG1000-1, for testing one break per phase (PII21166);
- BSG1000-2, for testing two breaks per phase (PII31166).
Each
BSG1000
is made of the following elements:
. No 3 BSG Remote Heads, of different types, connected close to the main breaker contacts.
a) Remote Heads for BSG1000- type1 :
. Measurement circuits for one contact;
. Each head has two cables, 2.5 m long, cross section 4 sq. mm, terminated with crocodile clamps,
for the current injection.
. Each head has one bipolar shielded cable, 3 m long, terminated with crocodiles, for the open /
close detection of the CB contacts.
- Each head has one 8 m long cable, terminated with a multi-pole connector, for the connection
between the remote head and the BSG Main unit.
