Contact us for more information on Calibration. The Megger Transformer Ohmmeter is a line-operated, field-portable instrument designed specifically to measure the dc resistance of all types of magnetic windings safely and accurately. Its predominant use is the measurement of the dc resistance of all types of transformer windings within the defined ranges of current and resistance. It can also test rotating machine windings and perform low-current resistance measurements on connections, contacts and control circuits. Three features combine to make this instrument unique: dual measurement, load tap-changer testing and safety shutdown. The dual set of potential inputs measure the resistance of the primary and secondary windings of a single- or three-phase transformer simultaneously. The dual reading characteristic will speed up the measurement when it is used to test windings on delta-delta connected windings on three-phase transformers. Due to circulating currents induced when the test current is applied to the primary winding, this type of measurement is countered by the same current on the secondary winding. This action attenuates the circulating current and the reading time is improved tenfold. The Transformer Ohmmeter is extremely useful when testing the windings and contact resistance on tap-changers with make-before-break contacts and voltage regulators. The internal shutdown circuit will be triggered by a voltage kickback of a few microseconds if the tap-changer contacts are opened when the tap-changer circuit is operated through all of the tap positions. This action will check for pitted or misaligned contacts as the instrument will shut down if either condition occurs. Users are protected by the shutdown circuit safety feature: any inadvertent disconnection of a test lead or loss of power to the instrument will safely discharge the energy stored in the test sample. The Transformer Ohmmeter's wide resistance range (1 micro-ohm to 1999 ohms) gives the optimum resolution for even the lowest winding resistance tested. - Direct digital reading saves time, no balancing is required. - Built-in discharge circuit safely discharges the specimen when test is completed, if lead accidentally disconnects or if power is lost. - Electromechanical safety indicator gives a visual indication of a charged or discharged specimen, even if power to the instrument is lost. - Two independent measuring channels allow simultaneous testing of primary and secondary windings or measurement of two phases at a time. - The sensitive surge detection circuitry monitors the contact operation of on-load tap-changers for the proper make-before-break sequence. If an open circuit condition exists, the instrument shuts down immediately. - High-accuracy, four-terminal bridge: no lead compensation required. - Electronically generated and regulated current supply overcomes high-inductance transformers quickly, allowing fast measurements to be taken. - Display of measurement occurs only after test current stabilizes. - Wide resistance range is suitable for testing a wide variety of transformers. - Lightweight and portable, the Transformer Ohmmeter is ideal for use in shop or substation environments. - Over-temperature protection provides automatic current shutdown and LED indication to prevent instrument damage. - Instrument and accessories come in a foam-lined transport case.
