Stator winding tester HZ-3310C

for transformersindustrialfor power systems

To meet the requirement for rapid DC resistance measurement of transformers, our company has developed a three-channel DC resistance tester specifically designed for YN-connected windings. The tester offers several advanced features, including simultaneous energization of all three phases, independent current and voltage sampling, and the ability to simultaneously measure and display the three-phase resistance values and the three-phase unbalance rate. This significantly reduces the test time required for measuring the DC resistance of transformers and addresses the issue of long test durations for each tapped winding of electric power transformers. The tester requires only one-third of the time compared to traditional methods. Performance Features 1.The instrument has a high current output and can automatically select the appropriate current, making it easy to operate. 2.Three-channel measurement allows real-time data collection, enabling simultaneous measurement of three resistance values and calculation of the three-phase resistance unbalance. 3.The instrument can measure all three phases simultaneously or use a single channel, as in traditional methods. It also includes a temperature conversion function for added convenience. 4.The instrument features a reliable and comprehensive protective circuit, ensuring safe operation. 5.A built-in calendar clock and the ability to store up to 500 sets of data, with retrieval and printing functions, offer enhanced usability. 6.The instrument allows users to set printing information, such as phase sequence and tapping position of resistance.
