Cable Connections
The cable compartment contains current transformers, voltage transformers (xed or withdrawable), and earthing switch, depending
on the individual operating requirements.
The cable compartment is constructed for installation of three current transformers. When all the three current transformers are not
required, dummies can be installed in their place to maintain the same instal
lation and connection procedures.
The xed or withdrawable voltage transformers are connected with busbar on the primary side and tted with HRC fuses. The earthing
switch can be operated manually, with position indication by mechanical indicator on the driveshaft and auxiliary switch. Three
lightning arrestors (optional) can be mounted in the space available.
