RECOMMENDATIONS

• SINGLE PHASE POWER PLANT WITH SINGLE PHASE POWER PLANT WITH PHASE CHANGER IS ECONOMICAL PHASE CHANGER IS ECONOMICAL WHERE DISRUPTION OF ONE PHASE WHERE DISRUPTION OF ONE PHASE BY EB IN PRACTICE BY EB IN PRACTICE

• EB METER CAPACITY SHALL BE EB METER CAPACITY SHALL BE 20AMPS PER PHASE20AMPS PER PHASE

• COST OF PHASE SELECTOR SWITCH COST OF PHASE SELECTOR SWITCH CAN BE RETRIEVED WITHIN ONE CAN BE RETRIEVED WITHIN ONE MONTHMONTH

RECOMMENDATIONS

• THREE PHASE POWER PLANT IS ECONOMICAL IN URBAN AREAS WHERE CONTINUOUS 3PHASE POWER SUPPLY IS AVAILABLE.
