I. Overview
HTJS-V Tan Delta Test Set 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 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 positive and negative connection 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.
