Metrel Website: Application Note Example
|
|
The Solutions section on our website is rich with information, presented in short application notes, about where and how to use our products. Some of these products are the high voltage insulation testers, which can be used for, among others, insulation testing of generator stator windings – as described in one of the application notes.

A few excerpts from the application note:
“… Temperature fluctuations inside the machine cause the moisture to condense in liquid form and seep in windings’ insulation...”
“… A 100 kW (3-phase, 50 Hz, 400 V / 195 A, 1000 r/min) generator was for about 10 years in use in a micro hydroelectric power plant…”
“… Generally speaking, a good rule of thumb is at least 1 MΩ of resistance for every kV. Though, this number (1 MΩ) holds true only at room temperature (20 °C)…”
