Product Introduction
The UHV-341 Transformer Tan Delta Tester is a precision instrument designed for measuring the dielectric loss tangent and capacitance of high-voltage power equipment. It is suitable for use in power plants, substations, workshops, laboratories, and research units. The tester uses frequency conversion technology to ensure accurate measurements even under strong electric field interference. It features an automated measurement process with a user-friendly Chinese menu interface.
