The 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.
