The above figures are based on the data obtained from Special Energy Meters (SEMs) installed in Northern Region.
Low Frequency conditions in March-2004due to
violation of IEGC permitted frequency band
The following figures relate to 15-minute time blocks under the ABT regime when the average frequency of the time block has been 49.0 Hz or below.. The total percentage of these low frequency blocks in March-2004 has been 16.02 %.
