1. Description
The CIRCUTOR MD-5060e is a smart, microprocessor-controlled, 5 kV
insulation tester. Besides the conventional measurement of insulation
resistances up to 5 TΩ, 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 500 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). Furthermore, the measured values are stored in a non-
volatile internal memory. Up to 4000 measurements may be stored, to be
transferred afterward to a computer running the CIR 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. 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.
