conductor, steel lattice tower and OPGW shield wire should be
supplied .The requirement of OPGW is for future use of SCADA
(Supervisory Control and Data Acquisition) Plant Control &
Monitoring and Energy Management system.
design and supply of four (4) Generator Vacuum circuit breakers for
Awash II & III HEPPs (supply only). The contractor should take
dimensions form the existing Generator circuit breakers before
designing & fabrications.
cable should be sufficient enough for over stretching from Yugoslav

sag he can make copies with his own expenses.
required 15KV overhead line is for a single circuit.
Contractor has the responsibility to test by his own equipment
for its effective installation and communications of the required
frequencies-Logging and archiving for the future with chronological
alarm signaling sequence, Logging of measurements for MW, Kwh,MVAR,
lgen. Vgen, 1 exc., Vexc. Cos Phi, Turbines bearings Temperature,
Generators windings & bearings Temperature, reservoir water level,
indication of the recording & archiving of the recorded values,
discharges of each until, all excitation parameters, etc., archived
data to be stored on the hard disk of the PC, where will be
accessible for further data treatment as necessary (data transfer),
switching ON/OFF of the circuit breakers & isolators, start/stop of
