Testing wind turbine lightning protection
The most significant danger facing wind turbines is damage from lightning strikes. Lightning faults cause more loss in wind turbine availability and production than the average fault. The number of failures due to lightning strikes is known to increase with tower height and a growing number of studies speculate that rotating wind turbines may be more susceptible to lightning strikes than stationary structures.

Determining harmonic direction
 Harmonics are caused by non-linear loads. Linear loads draw a linear current that follows the changing voltage of the AC waveform. Non-linear loads draw current pulses periodically, which creates distorted waveforms.

The Importance and Benefits of Portable Testing
A Portable Appliance Tester (PAT) is an instrument that is dedicated solely to the safety testing of portable electrical equipment in accordance with recognized national and local standards. Depending on locale, these standards may have been enacted into law. They may be requirements of specific industries or trade organizations, or just a good idea. In many cases, manufacturers of electrical consumer products who wish to export to foreign markets will be required, sometimes by national law, to assure the products have been safety tested. If testing is performed at time of manufacture, it will save money, aggravation and ill will that could result from having the products fail in the destination country.
