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. Powered by AC 220V, can contantly test transformer winding.
2. 6 gears output current, the max output current 20A, The min current less than 5mA, suitable for more kinds of transformers and mutual inductors.
3. Wide measurement range, high accuracy, 100uΩ-100kΩ.
4. Rapid response, directly switch on-load tap changer during testing, automatically reload datas.
5. Discharge alarm function, clearly display discharge, reduce missing operation.
5. Complete protective functions: can prevent the device from counter electromotive force impacting.
6. 7 inches high brightness LCD screen, clearly display in intense sunshine, and print testing results in real time.
7. RS485 telecommunication interface, transmitting datas to background.
8. Perfect parameters setting, can set the transformer's winding, tap changer position, phase group, object's temperature, covert temperature, etc.
9. Big storing capacity, max 500 groups datas.
