Tap Changer Analyzers & Winding Ohmmeters
-
Winding resistance test of inductive test objects, such as power transformers, is one of the most effective non-intrusive ways of checking its condition. Due to their advanced design, DV Power winding resistance meters provide high test currents (up to 100 A DC) and high accuracy (up to 0.1%) within light and portable test instruments. In addition to winding resistance measurement, it is also possible to perform simple, quick and reliable transformer on-load tap changer condition assessment by recording the test current during tap changer operation, also known as DVtest. Because of that, problems with a tap changer connection, contacts, and switching procedure can be detected.DV Power winding ohmmeters consist of single-phase RMO-T and three-phase TWA series. Models from the TWA series are designed for six-winding resistance measurement of power and distribution transformers, with only one single-step cable setup. As a result of reducing the total test time, it enables significant saving of time and money.Typical application areas of these instruments are high-voltage substations and industrial environments. They are intended to measure the resistance of:Transformer windingsOn-load tap changersGeneratorsElectrical motorsHigh-current bus bar jointsCable splicesWelding joints

Ohmmeters

GAOTek provides state of the art, professional grade Ohmmeters for sale to the United States, Canada and Globally. GAOTek Ohmmeters are portable instruments that accurately measure electrical resistance between two points on a circuit. The Ohmmeters have their own power supply through their own battery, and are needed when the two probes (red: positive side of circuit, black: negative side of circuit) are connected to the two points in the circuit where the desired measurement is to take place. The circuit is turned off, which is when the ohmmeter sends its own current through the circuit. Units of Ohms, symbolized by the Greek letter Ω (Omega), are used as a unit of measure when measuring electrical resistance. In accordance with Ohm’s law, when the current is passing through a circuit is at its maximum, the resistance is said to be the smallest.
