Cable Stealing Causes Blackout Oleh Administrator Sabtu, 22 Januari 2011 14:48 JAKARTA. Even there is no blackout because of power deficit; the fact is that the obstacle faced by PLN is not only from upstream side. Recently, blackout happened several times in Jakarta and surroundings because of loosing electricity components in PLN substations because of stealing by irresponsible people. Such as single core cable stealing happened in some substations in Kramat Jati, Cengkareng, Cikupa, Lenteng Agung, and Cikokol. Single core cable is a transceiver cable which distributes current from transformer towards Circuit Board for Low Voltage (PHBTR) which is located in every substation. PHBTR is a set of equipment used to share current which is distributed towards consumers’ house. Principally, single core cable is used in pair, so the distribution of current load from transformer towards PHBTR could be stable. For many cases, single core cable stealing is done by taking one cable from every pair which cause overheat and has to be faced by other cables. The most extreme effect causes fire because of this overheat and finally it causes blackout. Some single core cable stealing cases were done by cutting single core cable and change it with twist cable whose endurance is not everlasting such as happened in Cijantung, Cengkareng, Karawaci, and Cikupa. Because of this stealing, PLN lost Rp 209.000.000 in every substation. To anticipate the same cases, PLN regularly check substation once in every six months for 13.000 substations in all around Jakarta and surrounding and also install double lock in every substation. We advice citizen suspect every person coming to substation even using uniform and vehicle in PLN logo. Ask them the assignment letter and the identity. If they could not show both, then report to nearest PLN office or Call 123 and temporary arrest the person. People participation is highly hoped for goods and comfort. (AK) 1/1
