Electrical Test Instruments

Insulation resistances up to 10 TΩ Automated tests: absorption index, polarization index, capacitance, leakage current and AC/DC voltmeter Step voltage test Remote control through an Android app Auto-range Digital & bargraph reading Chronometer up to 90 minutes Switchable filter to remove external noise interference Real time clock and calendar Built-in printer 4,000 readings memory USB interface Software for data management Rechargeable LFP battery > The digital insulation tester model MD10KVx is TENTECHs cutting edge insulation analyzer equipment and it is one of the most complete and sophisticated available in the international market. A software allows for further analysis of tests results, including features such as graphical representation and automatic report generation. Its proven technology provides safe, reliable and accurate measurements of insulation resistances up to 10 TΩ, with 4 pre-selected test voltages, 500 V 1 kV 5 kV 10 kV. Other test voltages may be selected in steps of 25 V, 100 V or 500 V. A state-of-the-art microprocessor controls the equipment operation and enables the incorporation of advanced features which make measurements easier: auto-range selection, 4000 readings memory, AC/DC voltmeter, automatic measurement of absorption index and polarization index, leakage current and capacitance measurement, timer enabling programming of test duration, configurable pass-fail test, step voltage test, real time clock and calendar. Built-in chronometer, indicating elapsed time, in minutes and seconds, since the test started, up to 90 minutes. 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 real time clock and calendar, and the sequential test number, facilitates the identification of each test, and the organization of a predictive maintenance system by trend analysis. The MD10KVx has a Bluetooth interface that allows remote control of it through a Android device with TENTECHs app. With it you can take the photos of the objects under test and the GPS coordinates of each. It also allows you to record voice comments for each measurement. The MD10KVx is powered by a rechargeable LFP battery. 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.

Insulation resistances up to 5 TΩ 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 > 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. 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. The built-in chronometer automatically counts the elapsed time since the start of measurement. 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 real time clock and calendar, and the sequential test number facilitates the identification of each test and the organization of a predictive maintenance system by trend analysis. Some other advanced features are useful to run the most sophisticated insulation analysis. Step voltage test, configurable pass / fail test and timed measurements are automatically performed, with a very simple and user-friendly setup. The measurement parameters are stored in the non-volatile memory for an easy configuration. In order to guarantee the operator safety, the cabinet is made of a high breakdown strength plastic. High security output terminals are placed in the furthest and most protected area of the equipment. A light indicator shows high-voltage presence and is switched-off when the capacities (both internal and external) are discharged up to reaching a safe value. 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.
