1 TEST & MEASUREMENT DIVISION PC_F_ CA 6545/ Personal et confidential Megohmmeters 5kV C.A 6545 / C.A 6547 SALES PRODUCT INFORMATION Electrical testing and safety Cécile Le Goué

2 TEST & MEASUREMENT DIVISION PC_F_ CA 6545/ Personal et confidential The Experts in insulation at 5kV

3 TEST & MEASUREMENT DIVISION PC_F_ CA 6545/ Personal et confidential Measurements

4 TEST & MEASUREMENT DIVISION PC_F_ CA 6545/ Personal et confidential Functional specifications

5 TEST & MEASUREMENT DIVISION PC_F_ CA 6545/ Personal et confidential Other specifications

6 TEST & MEASUREMENT DIVISION PC_F_ CA 6545/ Personal et confidential A site-adapted hard casing, IP 67 when closed and IP 53 when opened A tool-bag containing all accessories Clamps and plugs are perfectly insulated and measurement leads are 3m long. A 3m guard lead is also supplied for high-insulation measurements. A special built-for-the-field design

7 TEST & MEASUREMENT DIVISION PC_F_ CA 6545/ Personal et confidential A studied ergonomic design A giant backlit LCD screen with digital display + bargraph Test voltage selection by rotary switch: • 4 pre-determined test voltages: 500 V 1000V 2500V 5000V • 1 programmable test voltage position: 40 to 5100V in 10V or 100V steps Measurement and function selection by pressing on a push-button

8 TEST & MEASUREMENT DIVISION PC_F_ CA 6545/ Personal et confidential For an excellent quantitative analysis... and qualitative analysis... Ø INSULATION measurement to 10 T  Ø VOLTAGE measurement to 5100 V Ø CAPACITANCE measurement of the tested circuit Ø LEAKAGE CURRENT measurement Ø automatic calculation of DAR, PI and DD ratios Ø R(t) graph plotting

9 TEST & MEASUREMENT DIVISION PC_F_ CA 6545/ 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.

10 TEST & MEASUREMENT DIVISION PC_F_ CA 6545/ Personal et confidential * DAR, PI ? 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
