Get Unique Winding Resistance Meters

The winding Ohmmeter is a line-operated, discipline moveable instrument made particularly to measure the dc resistance of all kinds of magnetic windings securely and accurately. Its predominant use would be the measurement on the dc resistance of all sorts of transformer windings inside the defined ranges of current and resistance. It could possibly also examination rotating machine windings and carry out low-current resistance measurements on connections, contacts and manage circuits. About three characteristics merge to create this instrument one of a kind: dual measurement, load tap-changer testing and protection shutdown.

The winding Ohmmeter WRM-10 is made to correctly calculate the winding resistance of highly inductive electric power transformers. The models dual resistance-reading input channels can measure two winding resistances concurrently. Four-wire (Kelvin) connections give superior precision voltage studying and call for no lead payment. The winding ohmmeter WRM-10 delivers stable resistance readings of pretty significant transformers by making use of a 36 Vdc electrical power deliver capable of outputting around ten Amperes. The resistance reading of the 100MVA transformer can be realized in five minutes or a lot less. The models strength deliver is cooled by heavy-duty enthusiasts created for continual procedure.

Considering that the winding Ohmmeter WRM-10 can correctly calculate winding resistances ranging from one micro-ohm to 2,000 ohms, it may also be employed to evaluate EHV circuit-breaker communicate with resistance, motor winding resistance, or any lower resistance. Also to measuring the resistance price, the WRM-10 also checks the make-before-break tap-switching sequences of voltage regulators and cargo tap changers.

The winding Ohmmeter WRM-10 is furnished with about three 50-foot exam cables, a floor cable, a power cord, and also a cable carrying bag. Every single exam cable lead is terminated that has a quick-disconnect examination clip.

Functional DESCRIPTION

The winding ohmmeter WRM-10s procedure is based for the electrical romantic relationship explained by Ohms regulation: R=V/I, in which I is really a recognised present-day and V is definitely the DC voltage calculated across the unfamiliar resistance. The worth with the unknown resistance is calculated by dividing the measured voltage by the present that is calculated by the microprocessor. Calculated winding resistance readings are then exhibited about the models back-lit Lcd display screen.

A exclusive current resource makes it possible for the winding ohmmeter WRM-10 to output approximately 10 Amperes of test existing. The winding resistance examination recent is mechanically adjusted dependent to the load resistance. For additional protection, the current resource circuit is thermally protected. Also, a built-in discharge circuit immediately discharges the saved vigor from the transformer with the end of every check.

Purposes

The Winding Ohmmeter is utilized:

one.To verify manufacturing unit examination reading through.

2.As part of a normal upkeep system

3.That will help locate the presence of defects in transformers, such as free connections

four.To test the make-before-break operation of on-load tap-changers

An everyday preservation software that features winding resistance measurements is easily the most effective way to use this instrument. At the time a benchmark is proven, subsequent test effects could be in comparison to determine if adjustments are occurring inside the transformers, instrument, transformers and related regulate wiring, voltage regulators, motors, generators, breaker contacts, every type of connections (bolted, soldered, crimped, and so forth.).
