Product Description

Product Description

Hand-held transformer turn ratio tester represents an innovative testing instrument engineered with a compact form factor to support handheld operation, delivering outstanding portability for on-site power asset inspections. This device is widely deployed to conduct transformer turn ratio group measurements, as well as polarity verification for potential transformers (PT) and current transformers (CT). Featuring rapid testing speed and superior measurement accuracy, it streamlines field diagnostic workflows for power transformers and instrument transformers.

In power substation maintenance and commissioning scenarios, transformer turn ratio and winding polarity are critical indicators to judge winding connection correctness, short-circuited turns and winding defects. Traditional bench-type turn ratio testers are bulky and inconvenient to transport to remote field sites. By contrast, this handheld model eliminates heavy setup work, allowing technicians to complete turn ratio scanning and polarity validation directly at the equipment location. It can reliably capture turn ratio data across all tap changer positions and confirm PT/CT polarity relationships efficiently, helping engineers identify hidden winding faults before they escalate into serious operational failures. Built to meet industry test standards, the tester maintains stable high-precision readings under variable on-site environmental conditions, making it a preferred tool for power utility teams, electrical contractors and transformer service providers.
