MI 3299 HV demo BOX - 1

Multi-purpose high-voltage demonstration box High voltage Demonstration Box 10kV has been developed for demonstration purposes at high voltage insulation diagnostics. It is equipped with high quality resistors in different ranges, high voltage capacitors and a discharge facility to simulate a breakdown phenomenon in gases. Additionally measurements of polarization index (PI), dielectric discharge (DD) and dielectric absorption ratio (DAR) can be demonstrated. Packed with all these features the demonstration box is also well suited for basic calibration of DC high voltage insulation resistance instruments. Highlights • 10 kV rated resistors with very low voltage coefficient • Resistive decade with 200 kΩ, 500 MΩ, 200 GΩ and 2 TΩ resistors • Demonstration of insulation breakdown in gases • HV capacitors in 2.5 μF and 5 nF range • Lightweight and portable design General specification • Dimensions (W × L × H) • Weight • Protection classification • Over-voltage category • Pollution degree • Degree of protection Reference conditions • Reference temperature range • Reference humidity range Operation conditions • Working temperature range • Maximum relative humidity Measuring and Regulation Equipment Manufacturer METREL d.d. Ljubljanska 77 SI-1354 Horjul Target applications: • Basic calibration of DC high voltage insulation testers • Demonstration of insulation diagnostics measurement with DC test voltage • Demonstration of HV insulation testers for sales purposes • Training centres, schools, laboratories Standard set: • Demonstration board MI 3299 • HV test leads, 2 pieces • User manual • Booklet
