Transformer winding resistance meters
The ATRM-203 and ATRM-403 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 Winding resistance ohmmeters ATRM-20 and ATRM-40 are the third generation transformer winding resistance meters. Designed specifically to measure DC resistance values of transformer windings, rotating machine windings, or any dc resistance of an inductive device.
The QLTCA-40 is Amperis winding resistance meter and load tap changer contact analyzer
The QLTCA-10 is Amperis winding resistance meter and load tap changer contact analyzer.
QRM-40 - The dual channels of resistance reading allow the user to measure two resistances of windings in the same test cycle. To ensure operator safety, the QRM-40 automatically discharges the energy stored in the transformer, after each test performed...
The model QRM-10P has all the features of the QRM-10 mentioned above, but also includes a 2.5" wide thermal printer, which can print test records on-site. Also, the test records can be downloaded to a computer...
QRM-10 - Low Resistance Ohmmeter, microprocessor-controlled, specially developed for large inductive loads. The QRM-10 has 10 A of test current, and can quickly provide a stable resistance reading for any large transformer...
