Electrical Safety and Clean Power

This is an educative and important guide for Electrical Equipment Safety. This can be also applied partially to Power Electronics and Home Energy Systems. Electronic Equipment also have to be maintained by Calibrating them and protecting them from environmental parameters like dust, grime, direct sunlight, moisture, humidity, sea wind (brine), corrosive fumes and chemicals. They should not be even placed near machines like a big lathe, sub-sonic or low frequency vibrations.

Electrical Safety is a Serious Issue Electrical Safety in the workplace is the most important job of an electrical worker. No matter how much training one has received or how much employers try to safeguard their workers, Electrical Safety is ultimately the responsibility of the electrical worker.

Earthing or Grounding is something Audio Enthusiasts make a lot of fuss about. The Articles here about Balanced Power, Symmetrical Power Systems and Earthing throw light on ways to counter Audio Noise.
Clean Power

AC Power has the 50/60 Hz noise, now more AC noise can be picked up by poorly designed systems when so many gadgets around. These articles are also relevant for the instrumentation engineer. Dissonance is encountered when you build sensitive strain gauge based measurements or while measuring and transmitting micro-volts from a remote sensor to the dashboard/control panel.
