3-Phase winding resistance meters ATRM 20/3 - 40/3
The ATRM-20/3 and ATRM-40/3 are three phase
transformer winding resistance meters that allow
the user to connect all test cables to the
transformer bushings. The unit will then measure
the transformer resistance value for each of the
phases without the need to disconnect and
reconnect cables for each phase. The ATRM-20/3
and ATRM-40/3 can provide a fast and stable
reading of very large transformers by utilizing a
60Vdc power supply. The ATRM-20/3 is capable of
outputting a selectable test current from 1A to
20A while the ATRM-40/3s test current is
selectable from 1A to 40A. Since both units can
accurately measure resistance from 1 micro-ohm to
500 Ohms (up to 2000 Ohms for the ATRM-20/3),
they can be used as micro-ohm meters to measure
EHV circuit breaker contact resistance, or for
any low resistance measuring application.
For a Delta transformer, the ATRM-20/3 and
ATRM-40/3 can measure the phase resistance
readings and provide the individual Delta winding
resistance values. The ATRM-20/3 and ATRM-40/3
can also provide the individual winding
resistance values for a Wye transformer without
the neutral terminal.

Winding resistance meters ATRM-20/ATRM-40
The ATRM-20 and ATRM-40 are Amperis third
generation transformer winding resistance meters.
The ATRM line is designed specifically to measure
DC resistance values of transformer windings,
rotating machine windings, or any dc resistance
of an inductive device. The ATRM line features
dual resistance-reading input channels that can
measure two winding resistances simultaneously
(primary and secondary windings of a transformer).
Both the ATRM-20 and ATRM-40 can provide a fast
and stable reading of very large transformers by
utilizing a 60Vdc power supply. The ATRM-20 is
capable of outputting a selectable test current
from 1A to 20A while the ATRM-40s test current
is selectable from 1A to 40A.

Transformer Winding Resistance Meters Load Tap
Changer Analyzer QLTCA-40
The QLTCA-40 is Amperis winding resistance meter
and load tap changer contact analyzer. The
QLTCA-40 is designed to accurately measure the
winding resistance of highly inductive power
transformers. The units triple resistance
reading input channels can measure three winding
resistances simultaneously.
Two-wire (Kelvin) connections provide high
accuracy and require no lead compensation. A
special feature of this device is its ability to
measure and graph the resistance trace of a
transformer LTC or voltage regulator contact
during operation. One resistance input channel is
dedicated to this feature. The QLTCA-40 provides
stable resistance readings of very large
transformers by utilizing a 60 Vdc power supply
capable of outputting a test current up to 40
Amperes.

Winding Resistance Ohmmeter QRM10P
The QRM-10P is designed to accurately measure the
winding resistance of highly inductive power
transformers. The units dual resistance-reading
input channels can measure two winding
resistances simultaneously, and four-wire
(Kelvin) connections provide high accuracy and
require no lead compensation.
The QRM-10P provides stable resistance readings
of very large transformers by utilizing a 36Vdc
power supply capable of outputting up to 10
Amperes. The resistance reading of a 100MVA
transformer can be achieved in 5 minutes or less.
The units power supply is cooled by heavy-duty
fans designed for continuous operation. For
greater flexibility in the field, the QRM-10P
comes with a built-in 2.5-inch wide thermal
printer used for printing test reports.
