Performance of energy saving lamps on power quality and luminous properties under voltage decreasing 240V?100V

As state-owned electricity company in Indonesia, PLN still has lack of capacity and long distribution network in several regions so that under nominal voltage still happens in those regions. Sometimes, a brownout strategy is still done to avoid outage, unfortunately it makes the voltage in area supplied by long network become worse in peak load. Lamps will operate at a lower voltage than their rating. Nowadays, energy saving lamps (ESLs) are widely used by customers in Indonesia. To investigate the effect of voltage decreasing on power quality and luminous properties, laboratory observations will be performed. Sixteen sample lamps consist of 5 CFLs lamps and 11 LEDs with different manufacturers and power ratings will be tested. The results of tests indicate that only a few of ESLs meet IEC 61000-3-2 requirements.
