Turn Ratio A Transformer Turns Ratio Meter is very useful as a tool for investigating problems associated with the core, the windings, and the tap changer of transformers and should be used for: - Identify shorted turns and finding turn error - Defective and incorrect tap setting - Finding mislabeled terminals and mislabeled nameplate Turns Ratio testing is a required test during the manufacture of transformers. It is too a part of a good routine preventative maintenance program as well as for Acceptance t Winding Resistance The WR-Line includes instruments to measure the winding resistance of all kinds of transformer, generators, motors... There are small battery operated instrumets from 15 Ampere up to rack mount versions with 100 Ampere measuring ranges. Winding resistance measurements in transformers are of fundamental importance for the following purposes: - Calculations of the I2R component of conductor losses. - Calculation of winding temperature at the end of a temperature test cycle. Micro Ohm Meter Raytechs digital micro ohm meters were designed for high degree of accuracy for the measurement of very low resistance. This technology was then packed into portable test systems for use by apparatus manufacturers, rebuild shops, and electrical maintenance crews. There are battery operated instruments with a measurement current of 10A and line operated systems up to 200A with a resolution of 0.01μOhm Software For all our instruments we offer a powerful software for free. It is a tool for remote control, data exchange and analysis. It runs on every windows based PC. A modern graphical user interface makes it easy and a pleasure to operate with it. Any missing feature can easily be added with a custom plug-in. Customized Systems Raytech produces customised transformer test systems. A modular design based on Raytech devices offers the possibility to create a custom solution for any application. It will drastically reduce measuring time and increase test performance.
