The Megabras MD-5060x is a smart, microprocessor-controlled, 5kV insulation tester and analyzer. Besides the conventional measurement of insulation resistances up to 5 TW, its advanced features allow to automatically measure both the Polarization Index and Dielectric Absorption Index, thus significantly simplifying testing of transformers.
This insulation tester is a portable, battery-powered equipment. Test voltage may be chosen from 500V to 5 kV in 100 dddV increments. Due to its measurement principle (actual voltage and current readings) the accuracy of resistance measurement is not affected by any test voltage error. Nevertheless, the High-Voltage generator is electronically stabilized with a better than 2% accuracy in open-circuit condition and for any normal operation battery voltage.
The MD-5060x is powered using a rechargeable battery and has an automatic charger that may be connected to 100 - 240V mains supply. The cabinet is strong and lightweight, easy to carry, impact-resistant and suitable to be used under severe weather conditions. Thus the megohmmeter supplies very reliable and accurate measurements both in laboratory and out in the field.
