Product Description
Anti-interference dielectric loss measuring instrument is a high accuracy instrument for power plants, transformer substations and so on to conduct full-automatic measurement of dielectric loss tangent value and electric capacity of various high voltage electrical equipment. Frequency conversion technology ensures accurate measurement under strong electric field interference. Chinese menu operation has been added to the instrument which has one-through operation. Microcomputer can automatically complete the measurement of the entire process. It is the most ideal dielectric loss measuring equipment now. The instrument is applicable to measure tgδ and capacity of high-voltage electrical equipment in workshop, laboratory, scientific research institution, etc.; It makes insulating oil loss test more convenient, simple and accurate.
The instrument can measure non-grounded and grounded high-voltage electrical equipment with positive and inverse wiring methods.
The instrument is equipped with high-voltage boosting transformer, and has taken zero-passage closing, lightning protection and other safety protection measures. It outputs voltage of different grades ranging from 0.5kV to 10kV during test, which ensures simple and safe operation.
