Vivid metrawatt provides sophisticated pc based winding testers for surge comparison. These type of instrument are mainly suitable for heavy electrical machines like alternators, motors and transformers in power generation and railway traction applications. They are useful for complete insulation and inter turn test, and have several advantages over cro based testers. Particularly test standards are nondeteriorating and facility for storage of waveform data of the entire lot of windings and machines for future references is available. Patented surgecomp software has made parallel processing possible resulting in high resolution digitisation. This means that one can directly read the phase and amplitude difference on the monitor and estimate the extent of damage. Different colours employed in display and printout make error-free identification. Custom design are also offered with this instrument.
