1. Description
The Megabras MD-5060x is a smart, microprocessor-controlled, 5 kV
insulation tester and analyzer. Besides the conventional measurement of
insulation resistances up to 5 T , 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 portable, battery-powered equipment. Test
voltage may be chosen from 500 V 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.
The built-in chronometer automatically counts the elapsed time since the
start of measurement. Measured values are transmitted through the data
output (USB) and are printed in the built-in printer (optional) 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
MegaLogg2 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 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.
The cabinet is strong and lightweight, easy to carry, impact-resistant and
suitable to be used under severe weather conditions. Thus the insulation
tester supplies very reliable and accurate measurements both in
laboratory and out in the field.
