Automatic Tan Delta Test Set Transformer Dielectric Dissipation Factor Tester
Main function
GDMZ Automatic Transformer Power Factor Tester, Transformer Tan Delta Tester is a high-precision instrument, which can be applied to measure electrical loss tangent and capacitance of all kinds of high voltage electrical equipment in power plants, substations, laboratory, etc.
Introduction
1. Intelligent Tan Delta Meter is a kind of instrument with high precision fully automatic measuring the dielectric loss tangent and capacitance of various high voltage electrical equipment in the power plants and substations. The adoption of frequency conversion technology could ensure the accurate measurement in the interference of strong electric field.
2. The operation instruction of the instrument is English, and other languages can be customized. The whole process is measured automatically through microcomputer. The instrument also applies to the measurement of Tan Delta and electrical capacity of high voltage electrical equipmentin the workshops, laboratories and research institutes.
3. It could measure non-grounded or grounded high voltage equipment adopting positive and negative connection method. Besides, it could measure the Tan Delta of capacitor voltage transformer and capacitance of main capacitor C1and C2.
4. The instrument is equipped with high voltage step-up transformer. Besides, it takes security measures like zero-cross closing, lightning protection, etc. During the experiment, different levels of high voltage ranging from 0.5KV to 10kV are outputted. The instrument has the advantages of convenient and safe operation.
5. Under the circumstance of oil dielectric loss ≥ 0.01%, with oil cup, positive wiring can be used to measure the dielectric loss of oil.
