Existing transmission line protection consisted of a basic overcurrent and earth fault device at each end. Voltex designed, configured, assembled, installed and commissioned a second set of protection for this line, utilising proper transmission line protection relays. As installed, these devices provide both an impedance-based system and also a differential protection scheme. The new relays work through the existing fibre optic communications network.
