what type of reply u are waiting for ? I remember last time that's a artical about how PUB charge us ... I remember it said that the power factor is not really taking into consideration. PUB only have rules for big power eater like factory/machine to have at least a power factor of 0.7++ (can't remember the figure) to maximise the usage. Also, those power saver selling outside which claim saving of 30% in your PUB bills is not true . The saving is only 5%+- I think , CASE stop a company from misleading customer few months back. |

But, correcting the powerfactor will reduce the reactive load (especially impt for poor quality extension/timers/old MCB). We are not charged for the reactive power but the reactive load is still on the circuit. That will heat up the circuit, higher voltage drop and may melt poor quality timers/extension. For safety reasons, its still good to mantain a good powerfactor to ensure that the entire electrical system is not overloaded by reactive power. |

in sg there is alot of accident with fire due to fish rearing during the luohan craze.
i think thats very important.. |

Dig out this thread again ... Anyone know how to measure active power ? Is there a meter around that can measure that ?

Bro .. just one question.
If you use a 50 uF capacitor, will it further improve the power factor ? |

If you are sway enough to hit the sweet inductance/capacitance resonance, it will cause it to have a impedence of 0 resulting in a huge surge of current flowing to yr lights. This will likely to cause explosion/fire/burnt out. |
