Live Tank Circuit Breaker
Since the test voltage for the Main Contacts is between 7.5 V and 15 V, it
is important to provide good connections between the Contact
Monitoring cables and the bushings. To relieve the clips of cable weight
and ensure better contact especially in windy conditions, wrap the
cables around the porcelain.
Measuring motion may be difficult for most live tank circuit breakers due
to the inaccessibility of the moving components.
Table 4.3 lists the circuit breaker adapters available.
