Yesterday afternoon in Nain, residents and businesses once again witnessed a power outage.
This afternoon, Karen O’Neill, Senior Communications Advisor for NL Hydro emailed us with the details.
She says it unfortunately affected all 428 customers in Nain between 12:58pm and 1:26pm.
According to O’Neil, a generating unit problem developed in one of the diesel units and caused the engine to slow down.
O’Neill said the engine slow down resulted in a voltage transfer between other on-line diesel units in the power plant.
Because of this transfer of load and voltage one unit automatically shut itself down, as it is supposed to do to protect itself from damage.
She says this in turn caused the other units to shut down due to the high load transfer from the shut down unit.
The Hydro crews assessed the problem, isolated the engine and then restored power to all customers.
O’Neill says NL Hydro apologizes for the inconvenience this may have caused.
