3.10 SOFT PROTECTION BAG, CODE PII19166.
The soft protection bag hosts CBA1000 and protects it against dust and scratches.
3.11 DOUBLE EARTH TESTER BSG1000, CODES PII21166 AND PII22166.
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, CBA1000 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 option does not allow to detect the pre-insertion resistance, as it is shunted by the ground
connections.
Two BSG1000 types are available:
- BSG1000-2, for testing two breaks per phase (PII21166);
- BSG1000-1, for testing one break per phase (PII22166).
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.
b) Remote Heads for BSG1000- type 2 :
. Measurement circuits for two contacts;
. Each head has three cables, 2.5 m long, cross section 4 sq. mm, terminated with crocodile clamps,
for the current injection on two poles.
. Each head has two cables, 2.5 m long, cross section 4 sq. mm, terminated with crocodile clamps,
for the short circuit of noise.
. Each head has two 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.
