VTSYIQI 10A Transformer DC Resistance Tester Transformer DC Resistance Meter with Resolution 1μΩ Output Current Automatic, 10A, 5A, 1A, 300mA, 100mA,<5mA  Accuracy 0.2% Automatic Data Refresh

Introduction

DC resistance is a mandatory test item for semi-finished products, finished products factory test, installation, overhaul, change of tap changer, handover test and preventive test of power department in transformer manufacturing. It can check the welding quality of the winding joints and whether there is any turn-to-turn short-circuit in the winding, whether the contact of each position of the voltage tap-changer is good and whether the actual position of the tap-changer matches with the indicated position, whether there is any fracture of the lead wire, whether there is any breakage of multi-stranded conductors in parallel winding and whether there is any breakage of strands, etc. The instrument adopts the new power supply technology. The instrument adopts a new power supply technology, with small size, light weight, high output current, good repeatability, strong anti-interference ability, perfect protection function and so on. The whole machine is controlled by high-speed microcontroller, with high degree of automation, automatic discharge and discharge alarm function. The instrument has high testing precision, easy operation, and can realise the rapid measurement of transformer direct resistance.

Feature:

The whole machine is controlled by high-speed microcontroller, with high degree of automation and easy operation.

The instrument adopts brand-new power supply technology with wide measuring range.

Perfect protection function, can reliably protect the impact of reverse potential on the instrument, more reliable performance.

Fast response speed, stable measurement data, automatic data refresh during the instrument test.

Intelligent power management technology, the instrument is always working in the minimum power state, effectively reduce the internal heating of the instrument, energy saving.

The instrument is equipped with an internal clock that does not lose power.

The instrument has an internal non-power-down memory, which can permanently save the data.
