Down­pour causes dis­rup­tion in elec­tric­ity sup­ply

Pakistan Observer - - KARACHI CITY -

KARACHI—K- Elec­tric in a state­ment here on Fri­day claimed that a large part of the city was re­stored with power in short time, de­spite the fact that the city faced heavy rain show­ers within a spell of 48 hours.

It fur­ther main­tained that such a down­pour was af­ter three years, where a large part of city in­fra­struc­ture was in­un­dated with clogged sew­er­age, wa­ter drains and nul­lahs.

The state­ment pointed out that ini­tially a high num­ber of feed­ers were tripped, out of which 50% were reen­er­gized in less than one hour, and the ac­tual num­ber of af­fected feed­ers on ground were over 280 on day one and around 160 on day two.

Most of th­ese feed­ers were en­er­gized within a short span of one to five hours on both days of rain. How­ever, there have been small pock­ets in dif­fer­ent ar­eas of the city which faced longer out­ages due to lo­cal­ized faults of PMTs, Kunda in­fested ar­eas with short ca­bles or wa­ter logged ar­eas which af­fected the un­der­ground ca­bles.

The press re­lease fur­ther stated that Karachi has a unique at­mos­phere in which hu­mid­ity, sea wind and saltish mois­ture de­posit residues on ca­ble joints, jumpers etc. In this en­vi­ron­ment if rain in­ter­val of coastal city is more than few years then th­ese mois­ture de­posits hard­ens on line joints and jumpers, which badly im­pacts the line with sud­den rain.

Due to this rea­son the num­ber of af­fected feed­ers on day two were less than the first day, and con­tin­ues to re­duce with each sub­se­quent rain. Un­for­tu­nately in­fre­quent rains in Karachi due to global cli­mate change mag­ni­fies this prob­lem.

Ad­di­tion­ally, parts of Karachi with katchi abadis and power theft ar­eas, with abun­dance of kun­das adds to the prob­lem of short cir­cuit­ing and sit­u­a­tion is fur­ther de­te­ri­o­rates due to wa­ter log­ging, where some feed­ers had to de­lib­er­ately put off due to safety rea­sons, and con­se­quently peo­ple face longer out­ages.

The K- Elec­tric field teams and cus­tomer call cen­ter, in­clud­ing the man­age­ment has been work­ing 24 hours to en­sure sup­ply and restora­tion of power to the Cos­mopoli­tan de­spite the stated chal­lenges.

As a re­sult of KE team ef­forts there has been no ma­jor dam­age to power in­fra­struc­ture and the lo­cal­ized faults are be­ing re­stored. K-Elec­tric ex­tends ‘sin­cere apol­ogy’ to its cus­tomers for in­con­ve­nience caused by un­con­trol­lable fac­tors, and con­tin­ues to re­store power as quickly as pos­si­ble, the state­ment added.—APP
