Product Description
Handheld DC Resistance Tester MYFT Portable Touch Screen Transformer Winding DC Resistance Test Equipment with Data Storage Function for Power Substation Maintenance
This high-accuracy, battery-powered DC micro-ohmmeter is designed for measuring DC resistance in small and medium-sized transformers, generators, motors, and mutual inductors. Featuring multiple current gears to accommodate various measurement requirements, the instrument comes standard with lithium batteries for convenient field operation.
Product description
Transformer DC resistance is a must-test item for semi-finished products and finished products in transformer manufacturing, factory testing, installation, overhaul, after changing the tap changer, handover test and preventive test of the power department. In order to meet the need for rapid measurement of transformer DC resistance, our company has developed the MYFT handheld DC resistance tester. This instrument adopts new power supply technology and has the characteristics of small size, light weight, large output current, good repeatability, strong anti-interference ability, and complete protection functions. The whole machine is controlled by a high-speed microcontroller, has a high degree of automation, and has automatic discharge and discharge alarm functions. The instrument has high testing accuracy and is easy to operate, and can quickly measure the direct resistance of the transformer.
