SYNOPSIS POWER QUALITY IN MODERN FACILITY

The increased usage of Variable Speed Drive, Computer and Energy Saving Lighting in modern building has brought about reduced energy usage and increased productivity. However, this also place higher stress on the electrical network due to harmonics pollution, irregular power factor swing and voltage stability problem. The operation of any non-linear load such as inverter circuit in speed drive, computer power supply and electronic ballast in lightning system introduce a current and voltage condition known as harmonics distortion on the network power line. In some cases, the stability of the network during critical time may falter due to unexpected condition of how the network interact with UPS and backup generation supply. Consequence of power quality issues may result in catastrophic failure of capacitor system, intermittent disruption of computer & micro-processor circuit, hot spot at bus bar and panel cable terminals.

This talk covers on the following areas:
1. Underlying technical fundamental of the sources of harmonics pollution and how  to identify it objectively
2. Review on International Standard that helps to assess the severity of a PQ Condition
3. Current state of the art solution to mitigate PQ condition
4. Case studies on some critical facilities PQ event, the learning and option
5. Q&A
