UHV-341 Transformer Tan Delta Tester is a kind of instrument with high precision fully automatic measuring the dielectric loss tangent and capacitance of various high voltage electrical equipments in the power plants and substations. The adoption of frequency conversion technology could ensure the accurate measurement in the interference of strong electric field.
The operation instruction of the instrument is English. The whole process is measured automatically through microcomputer.
The instrument also applies to the measurement of tgδ and electrical capacity of high voltage electrical equipments in the workshops, laboratories and research institutes.
It could measure non-grounded or grounded high voltage equipments adopting UST and GST method. Besides, it could measure the tgδ of capacitor voltage transformer and capacitance of main capacitor C1and C2.
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.
Under the circumstance of oil dielectric loss ≥ 0.01%, with oil cup, positive wiring can be used to measure the dielectric loss of oil.
This following protection features are included in this instrument:
High voltage short-circuit protection
CVT over-voltage protection
Poor grounding protection
