Quick technical question for the electrical engineers on forum

[square_wave]

What are the different electrical parameters which needs to be tested to figure out if the electricity coming to your home is alright ?

- Voltage
- Earthing
- Anything else ?

Hi,
Other things you may check are:
1. Harmonics
2. Frequency (its not always 50Hz!)
3. Noise (The A/C waveform may not be perfectly sinusoidal... again the sine-wave itself may be riddled with kinks in the "S" waveform)

While earthing and voltage are pretty easily checked by your local electrician, for Harmonics and Frequency you need specialised equipment.

BTW I'm not an elec engineer. I came to know reg above from the elec consultants I coordinate with, in construction industry.

Regds,
