The ADTR-2k is a versatile test set used
for measuring the Dielectric Constant (ε), Tan Delta
(Dissipation Factor), Power loss, Resistance & Resistivity
of transformer oils, other electrical insulating liquids and
solid insulating materials in sheet form. The ADTR-2k is only
the measuring instrument – in order to test insulating
liquids, it should be used with a three-terminal oil test
cell. A heater is required when testing oil at temperatures
specified in international or national standards. A suitable
solid dielectric test cell is required for testing insulation
in sheet form.
When excited with an AC source, the ADTR-2k measures the
Voltage, Capacitance, Dielectric Loss and Frequency. To determine
the Dielectric Constant (ε) , the measurements are
carried on an empty and a full test cell. The parameters of
the test cell can also be entered manually, using the keypad.
The operating procedure is menu driven & simple. The
AC & DC test voltages are set using the front panel keypad.
Tests can be programmed for the AC test, between 200 and 2,400
volts. The DC test can be programmed between 100 and 1,000
volts.
After initial set-up, the oil test cell has to be filled
with the sample oil and the test procedure initiated. The
ADTR-2k performs all the selected measurements automatically
and the results are then displayed on the front panel. The
test results can be transferred to a PC using the RS-232 interface,
printed out using the Centronix parallel port, or stored in
a non-volatile memory. The tests can also be repeated.
