5kV Digital Insulation Tester MD5060x
The TENTECH MD5060x is a smart, microprocessor-controlled, 5 kV insulation tester. Besides the conventional measurement of insulation resistances up to 5 TΩ, its features allow to automatically measure both the polarization index and dielectric absorption index, thus significantly simplifying testing of transformers.
Features:
- Insulation resistances up to 5 T&Omega
- Auto-range
- Guard terminal
- Digital & bargraph reading
- Alphanumerical display
- Programmable timer
- Automated tests: absorption index and polarization index
- Step voltage test
- Programmable pass-fail
- Real time clock and calendar
- Built-in printer
- 4000 readings memory
- USB interface
- Rechargeable LFP battery
- Auto power-off
- Software for data management
This insulation tester is a portable, battery-powered equipment. Test voltage may be chosen from 500 V up to 5 kV in 100 V 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.Measured values are transmitted through the USB interface and are printed in the built-in printer as a registration of the performed test. Furthermore, the measured values are stored in a non-volatile internal memory. Up to 4000 measured values may be stored to be transferred afterward to a computer running the T-Logger program. This software allows a further analysis of the test results, including a graphical representation and automatic report generation.
The MD5060x is powered by a rechargeable LFP battery and has an automatic charger that may be connected to 100 – 240 V mains supply (AC Adapter). 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.
