a. The Circuit Breaker is OLD and has CTs on the bushings. Since this is a Tariff Metering Point, the CB
mechanism box has seals therefore will make the installation works complicated.
b. The space in the Control room is limited therefore no adequate space for any type of panels.
c. The 2 No. of isolators do not have Auxilliary Switches.

ii. Installation and adaptation works
a. The Equipment/Control room is permanent and is therefore appropriate for SAS Equipment.
b. 33kV CB and Transformer functions (Protection and Voltage Regulation) are all wired to the existing
panels therefore possible to capture signals for the SAS. The Relay panels wiring are in good condition.
