The tester can be used to test:
Sensitive objects: transformer, mutual inductor, reactor, etc;
Resistive objects: conductive wire, switch contact, copper bar, etc.
The DC resistance test of transformer winding is an indispensable test item after transformer is transferred, overhauled and changed. It adopts new power technology, with stable performance, quick measurement, compact size, easy to use, high precision of measurement and good repeatability of data. It is the ideal equipment to measure the DC resistance of transformer windings and high power inductance devices.
Product Features:
1. The instrument is controled by single chip microcomputer, highly automation, easy to operate.
2. 5 gears output current: 2.5A, 5A, 10A, 20A, 40A.
3. Adopts high frequency switch power technology, large output current, suitable for medium or large transformer's winding test.
4. Perfect functions, preventing the instrument from counter electromotive force impacting, reliable performance.
5. Rapid response, directly switch on-load tap changer during testing, automatically reload datas.
6. Discharge alarm function, clearly display discharge, reduce missing operation.
7. Intelligent power management technology, the instrument works under the minimum power state, effectively reduce heat, save energy.
