Riverside Electrical currently has an electrician working on a project in Highland.
In our last post we were discussing surveying power quality options. This is a continuation of that last post.
In the years since the Electrical Power Research Institute’s survey, there has been a huge increase in the use of switchable power supplies for personal computers, Internet servers, and other computer technology has seen a dramatic increase. Variable speed drives in manufacturing facilities, varistors, and rectification circuits to supply electronic loads, step motors, and similar devices, all of which can create a fair amount of “dirt” in a power system, have seen similar increases. Along with equipment such as arc furnaces for steel plants, these devices affect the quality of power received by others.
A facility that requires clean power to avoid disruptions to its processes (such as a plant making semi-conductors) might experience a fleeting, possibly harmful dimming of power when a neighbor (such as a steel mill or furnace) turns on a particular load. A major auto plant that manufactures axles recently determined that a 1/10 of a second (six-cycle) disturbance would cost the company about half a million dollars because major loads have to be reset and restarted, causing a loss of about an hour in production. The price of the power quality equipment to test for and protect against sags and swells, harmonic distortion, line noise, and high-energy transients spurred by lightning-induced surges and power company switching that can destroy electronic components instantly, can, for some industries, start to seem modest by comparison.
