Power Factor / Grading Capacitance Measurement - OMICRON
WebExamine power and control wiring with the thermal imager, looking for loose connections. A thermal evaluation will identify a bad connection by showing a temperature increase due to the additional resistance at the point of connection. A good connection should measure no more than 20 degrees above the ambient temperature. WebTests for insulation breakdown. By using a higher voltage it can push through weak spots and get a more accurate measurement. Power factor (doble) testing tests the capacitance (and power factor) by using AC voltage. Capacitance is reactive to frequency so AC close to 60Hz must be used to be accurate.
