Voltage transformers:
The voltage transformers are mounted inside the
switchgear at the rear. They are connected with
preassembled internal primary cables to the circuit-
breaker in the most right panel (number 3). Also the choke
coil and the resistor for the anti ferro resonance filter
connected to the tertiary windings are mounted in this part
of the switchgear. The connections on the voltage
transformers are made with earth screened connectors
type A. The connections on the cable cones of the circuit-
breaker (panel 3) are made with earth screened
connectors type C, mounted in parallel with the
connectors for the primary cables. Due to the limited
mounting space inside the cable compartment these
connectors are make Tyco type RSTI 58 and RSTI CC58.
Current transformers:
The current transformers for metering and protection of
the circuit-breaker (panel 3) are mounted inside the cable
compartment around the primary cables. They are
mounted on a metal sub frame for easy
removing/remounting without disconnecting the secondary
wiring when the primary cables are mounted.
