Product Description

General Information

Transformer DC winding resistance is a required test item for the factory test, installation, overhaul, change of tap switch, handover test and preventive test of power department. It can check the welding quality of the winding joints and whether there is a short-circuit between the windings. It can detect whether the contact of each position of the voltage tap switch is good, and whether the actual position of the tap switch is consistent with the indicated position, whether there is a fracture of the lead wire, whether there is a broken strand of multi-strand wire and winding.

MY-RD Transformer DC Winding Resistance Tester is designed in order to meet the needs of rapid measurement of transformer DC winding resistance. The instrument adopts a new power supply technology, featuring small size, light weight, large output current, good repeatability, strong anti-interference ability and perfect protection function. The whole machine is controlled by high speed single chip microcomputer, high automation, with automatic discharge and discharge alarm function. The instrument has high precision and easy operation, which can realize the rapid measurement of transformer DC winding resistance.

Key Features
  • High-speed microcontroller control with full automation and intuitive operation
  • Advanced power supply technology with multiple current ranges and extensive measurement capabilities
  • Temperature conversion function for both copper and aluminum materials with touch input for winding temperature and conversion temperature
  • Comprehensive protection system that reliably safeguards against back electromotive force impacts
  • Audible discharge alarm with clear discharge indicators to prevent operational errors
  • Rapid response capability allowing direct on-load tap changer switching during measurement with automatic data refresh
  • Seven-inch color touchscreen display with freely switchable Chinese/English interface
  • Built-in perpetual calendar clock with power-off storage capacity for 1,000 test datasets
  • RS232 and USB interfaces for computer communication and USB flash drive data storage
  • Mobile app compatibility for remote control and test data upload via software
