The federal government has been driving the process to develop an interconnected standard to establish the criteria and requirements of distributed generation (also called distributed resources or dispersed generation) to be connected into the utility-owned electric power grid. READ MORE

In an attempt to simplify complex mathematical equations, the summary value for harmonics called total harmonic distortion (THD) is derived from the individual harmonic values. The individual harmonic values are a magnitude (and phase angle) at the frequencies that are integer multiples of the fundamental frequency. In North America, these are 120 Hz, 180 Hz, 240 Hz, 300 Hz, and so on. READ MORE

As commercial, industrial and educational facilities become more dependent on information technology (IT) equipment for performing the day-to-day tasks, the quality of electrical supply that powers these growing loads becomes more of a factor. More and more people are becoming aware that power quality needs to be part of the productivity equation. READ MORE

A presentation at the PQ World 2002 Conference in October re-enforced the need to continue to make the electrical workplace a safer place to work in. While it would be ideal, it’s not always possible to de-energize electrical systems before working on them. READ MORE

Due to the proliferation of TVSS (transient voltage surge suppressors), while voltage transients are still here, they may not be captured by most power-quality monitors much longer. READ MORE

* For referenced figures, please refer to ELECTRICAL CONTRACTOR magazine. If the data recorded appears to violate the laws of physics, apply the test of reasonableness to the data before attempting to fix something that isn't real. READ MORE

A single-phase, rectified input, switching power supply will have a sharp reduction in current at the beginning of a sag, followed by an increase in current to a value greater than the original current levels, until the sag has ended or the equipment trips off line. READ MORE

Please see Electrical Contractor magazine for referenced Figures. -------------------------------------------------- A periodic voltage sag on a single-phase line occurring approximately every 30 to 60 seconds, accompanied by a sharp increase in resistive current and/or a sharp increase in the neutral-to-ground voltage, is probably due to a laser printer, copy machine or similar type load.
