The transformer DC resistance tester is a crucial testing tool used for various purposes in transformer manufacturing. It serves as a necessary test item for semi-finished products, finished products in factory testing, installation, overhaul, tap changer replacement, handover tests, and preventive tests conducted by power departments.

Description 


This Transformer DC Resistance Tester performs several critical functions, including checking the quality of welding joints in the winding and identifying any inter-turn short circuits within the winding. It also assesses the integrity of the contact points in the voltage tap changer, verifies the alignment of the tap changer's actual position with the indicated position, inspects for broken connections in the outgoing line, and identifies any broken strands in the parallel winding of multiple wires.


Features


  • High resolution 65K true color 7 inch touch screen with high brightness and clear display under strong light.

  • The sampling instrument is powered by internal battery or power adapter, which is convenient for outdoor operation.

  • It has the temperature conversion function of copper and aluminum, which can be converted to the resistance value at different temperatures according to the customer's needs, so as to facilitate data comparison.

  • Digital management of power supply battery, with functions such as residual power display, residual power alarm, over-current protection, etc.

  • It has power off free data storage and perpetual calendar, which can store 1000 groups of test data and test time in real time.

  • It has a U disk interface.

  • It has protection functions such as discharge audible alarm, power overheating, reverse voltage connection, etc.

  • The maximum 10A measuring gear test current is convenient for measuring the low voltage side resistance of large capacity distribution transformer.

  • The on load switch can be directly switched in the measurement state, and the instrument automatically refreshes the data without resetting.
