UHV-340 Transformer Tan Delta Tester -Catalog

Product catalog summary

Product Introduction
The UHV-340 Transformer Tan Delta Tester is a high-precision, fully automatic instrument designed to measure the dielectric loss tangent and capacitance of high voltage electrical equipment in power plants and substations. It utilizes frequency conversion technology to ensure accurate measurements even in strong electric fields.

Product Features
The instrument operates with English instructions and automates the measurement process via a microcomputer. It is suitable for measuring tgδ and electrical capacity in various settings, including workshops and laboratories. It can measure both non-grounded and grounded high voltage equipment using positive and negative connection methods. The tester is equipped with a high voltage step-up transformer and includes safety features such as zero-cross closing and lightning protection. It can output high voltage levels ranging from 0.5KV to 10kV, offering convenient and safe operation. Additionally, it can measure the dielectric loss of oil with an oil cup when the oil dielectric loss is ≥ 0.01%.

Protection Features
The instrument includes high voltage short-circuit protection, CVT over-voltage protection, and poor grounding protection.
