https://www.mktester.com/transformer-tester/transformer-dc-resistance-tester/three-channel-dc-resistance-tester.htmlProduct description：To satisfy the requirement for quick measurement of DC resistance of transformer, our Company has developed three-channel, DC resistance tester aiming at YN connection winding. The tester can fulfill functions such as simultaneous energization on three phases, independent current sampling, voltage sampling, as well as simultaneous measurement and display of three-phase resistance value and three-phase unbalance rate, thus can significantly reduce test time for DC resistance of transformer, solve the problem of long test duration for DC resistance of each tapped winding of electric power transformer. It requires only 1/3 of the time required by traditional method.
