Low Voltage Power Supply Problem

Common issues with power supply may 6th 2016 filed under power quality common problems with power supplies explained.

Low voltage power supply problem. Series regulator when a series regulator power element shorts the output very quickly rises above the rated voltage of the power supply. In technical terms to explain this the low voltage refers to a 90 percent reduction of current compared to its normal level. Among other things one problem is that the gauge of wire that was sufficient to supply 200 000 people will be too small to satisfy the demand of 400 000 people. If you have a voltage drop or sparking at any of the electric wall outlets in the home then you more than likely have an issue with low voltage.

A real life example of such a problem involved a hospital technician who tested a circuit for two days before installing patient monitoring equipment. The only way to limit this is to trip ovp and either fire an scr across the output to bring the voltage back down or open output relays. Three things can happen when the power supply is insufficient voltage fluctuations power surges. There are a number of problems which may occur with the incoming power supply to a site.

If a city of 200 000 people is properly wired a sudden increase in population will strain the system. To fix wall outlet voltage you need to do a bit of investigating to get to the true issue and fix it. It could be a loose wire or a problem at the panel. These problems cause voltage and current instability which can have a significant impact on equipment operation and power usage.

One instance of voltage harmonics amounting to 5 2 percent thd was noted. A bad power supply can be the root of many pc problems. Experience can help a tech diagnose problems caused by a faulty power supply that would normally be overlooked by a novice. Low voltage problems could be the result until the wires are replaced.
