The AC/DC test transformer employs advanced manufacturing techniques, featuring epoxy vacuum‑impregnated windings and a CD‑type core. Compared with conventional oil‑immersed transformers, it boasts significantly reduced weight and compact dimensions, while delivering superior insulation strength and enhanced moisture resistance. It also effectively minimizes magnetic leakage, greatly improving the transformer’s ability to withstand short‑circuit currents during testing. With its small footprint, light weight, compact design, comprehensive functionality, and ease of use, this equipment is ideally suited for power utilities, industrial and mining enterprises, and research institutions. It finds widespread application in lighting systems, machine‑tool electrical equipment, electromechanical devices, medical equipment, rectifier installations, and more. Its performance fully meets the diverse specialized requirements of users, making it an indispensable instrument for performing power‑frequency withstand voltage tests and DC leakage tests on high‑voltage electrical equipment, components, and insulating materials.

When a transformer DC resistance tester exhibits quality issues, a timely maintenance plan should be formulated and on-site troubleshooting carried out promptly. If the instrument malfunctions, please contact the supplier without delay to ensure targeted resolution. During the warranty period, the manufacturer will provide free on-site technical support and equipment‑operation training. Please note the warranty terms: in the event of abnormalities or failure to meet technical specifications, an unconditional replacement is available. Standard electrical testing instruments typically come with a three‑year warranty and lifetime maintenance.

Proper operation of the transformer DC resistance tester according to the instructions: DC power supply check: Close the main power switch; the corresponding indicator light will illuminate. Press the “Start/Stop” button to begin the test. Once the DC resistance measurement is complete, turn off the main power switch; the indicator light will extinguish. After discharging, reposition the test leads and proceed with another measurement.
