9. TEST & MEASUREMENT DIVISION PC_F_ CA 6545/47 - 9 Personal et confidential Reminder Insulation resistance measurement qualifies the degree of insulation in installations or equipment. It also serves as a basis for preventive maintenance. Insulation measurement is very sensitive to variations in temperature and humidity. While testing, measurement is also initially influenced by unwanted currents. So, it is best to carry out : ä quantitative measurement of long duration: provided by mode " Time-controlled testing " and R(t) graph plotting ä a qualitative analysis with calculation of DAR, PI and DD ratios.

A qualitative analysis can turn out to be more clever and reliable than a simple quantitative analysis: the calculation of DAR and PI ratios enable the user to ignore climatic conditions and unwanted currents liable to invalidate measurement results. reminder : DAR = R 1mn / R 30s &PI = R 10mn / R 1mn * DD ? This test is especially suited for measurement on heterogeneous and multi-layer insulation, for it can reveal a defective layer among layers with high resistance. We recommend charging the insulator with 500V for 30 minutes. DD = I 1mn (current measured after 1mn (mA)) Test voltage (Volt) x Capacitance measured (Farad) * R(t) graph plotting : w hen a time-controlled test begins, measured insulation samples are automatically memorized. It is possible to follow insulation evolution in function to the test voltage's application duration. Then R(t) graph can then be plotted out either by hand or directly on a PC screen using the MégohmView software. Reminder
