T&R Test Equipment is a market leader in the field of current
injection equipment. The range includes secondary injection
units with 100A output capability up to 6000A primary
injection systems. All have true RMS metering, a flexible
timing system, and an easy to understand user interface.
The 200ADM is one of a new generation of products, and
provides commissioning and maintenance engineers with a
flexible system for testing protective systems. It has an easy
to understand panel layout and a simple user interface. The
status of every function can be seen at a glance, and there
are no complex menus to navigate.
The unit has a range of outputs allowing injection of currents
as low as 1mA and as high as 200A. Voltages up to 240V
are available on the main outputs, allowing high impedance
current relays and voltage relays to be tested. Four true
RMS metering ranges are provided, allowing the full scale of
the meter and trip level to be set independently of the
selected output. Industry standard safety connectors are
used on all inputs and outputs for convenience, reliability and
safety.
The 200ADM is comprehensively protected by overcurrent,
duty cycle and thermal trips, and keeps the user fully
informed of any trip condition.
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
An auxiliary metering input is provided and can measure AC
and DC voltage, current, frequency, and the phase between
the main current output and an external voltage or current. A
stabilised DC supply is provided to power the relay under
test, along with an independently variable AC output.
The timing system is very flexible without compromising ease
of use, allowing trip times, reset times and reclose times to be
quickly measured to a high degree of accuracy.
The 200ADM can be used to test many types of single phase
secondary protection including:
•
Over and under current relays
•
IDMT relays
•
Over and under voltage
relays
•
Auto-reclosers
•
Time delay relays
•
Differential relays
•
Earth fault relays
•
Miniature circuit breakers
•
Power relays
•
Tripping relays
•
Thermal relays
