HZ-2000H Automatic 12kV CVT Capacitance And Tan Delta Meter
I. Overview
The automatic capacitance and tan delta test set is a high-precision, fully automatic instrument designed to measure the dielectric loss tangent (tan δ) and capacitance of various high-voltage electrical equipment in power plants and substations. The adoption of frequency conversion technology ensures accurate measurement even in the presence of strong electric field interference.
The instrument features an English-language operation interface. The entire measurement process is fully automated through microcomputer control.
This instrument is also suitable for measuring tgδ (dielectric loss tangent) and capacitance of high-voltage electrical equipment in workshops, laboratories, and research institutes.
It could measure non-grounded or grounded high voltage equipments adopting positive and negative connection method. Besides, it could measure the tgδ of capacitor voltage transformer and capacitance of main capacitor C1 and 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 12kV 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 not included in this instrument:
• High voltage short-circuit protection
• CVT over-voltage protection
• Poor grounding protection
