Description
The unit has a range of outputs allowing injection of currents between
1mA and 200A. Voltages up to 240V are available on the main outputs
allowing high impedance current relays to be tested. True RMS metering
with single cycle capture is provided. 4 current ranges allow the full
scale of the meter and trip level to be set independently of the selected
output. Industry standard safety connectors are used throughout for safe,
reliable convenience.
The 200ADM-P has a flexible auxiliary ac output
that can be used at up to 260V for voltage relays or up to 10A for current
relays. The phase and frequency of this output are fully adjustable. This
combination of voltage and current allows testing of relays that require
two voltages, one voltage and one current or two currents.
An auxiliary metering module is provided that
meters ac and dc voltage, current and frequency from the auxiliary outputs
or external signals. The module can also take measurements in conjunction
with the main current output to meter phase angle, power, impedance, CT
ratio and harmonics.
A variable stabilized DC supply with current
limit is provided to power the relay under test.
The unit has a comprehensive timing system linked
to the outputs allowing trip times, reset times and reclose times to be
quickly measured to a high degree of accuracy. The timer includes a
current operated mode and can accurately test instantaneous trips.
Two USB host sockets are provided to connect a
memory key, keyboard or printer. Results of every test can be stored to
the memory key in spreadsheet format for later analysis. The keyboard
allows entry of a comment against each result. In addition a graphics file
of the waveform may be stored to the memory key. Harmonics analysis
results can also be recorded.
The back-lit display on
the 200ADM is bright and clear with a wide viewing angle. The
results of a test can be seen here as they appear on the display
