Measurement transformer around the group and large power inductor dc resistance ideal equipment
Note: Regarding product purchase, technical maintenance and other services, welcome to send email:
Direct resistance test apparatus is an indispensable experiment project for transformer after handing in pick up, overhaul and sub-pick up switch. In general, using traditional methods (bridge method and pressure drop method) measurement transformer winding group and dc resistance of large power inductance equipment is a time-consuming and time-consuming work. In order to change this situation, shorten measurement time and reduce the work burden of test personnel, Wuhan UHV developed Dc resistance rapid test instrument (hereinafter referred to as direct resistance instrument). It adopts new power supply technology, featuring stable performance, rapid measurement, small volume, easy to use, high measurement precision and good data repeatability. Measurement transformer around the group and large power inductor dc resistance ideal equipment.
Direct resistance test apparatus meets the requirements of DL/ t845.3-2004 with national standard GB6587 "general outline of electronic measurement instrument environmental test" and GB6593 "test rules of electronic instrument quality".
