Product Description

Automatic Capacitance & Tan Delta Tester

JXJS-10 automatic capacitance& tan delta tester has bridge, variable frequency converter, AC testtransformer and standard capacitor inside. It can be used to measure thedielectric loss on site (power plants or substations) or in the lab (loadcapacitor, capacitive voltage divider, current transformer, grading capacitors,surge arresters, shunt reactors, bushings, etc ). It has tunable frequency andanti-interference function. 


(1) With big LCDto show the measurement data;

(3) Automaticallyrecognize the test object whether it is capacitive, inductive or resistive,easy operation;

(4) Can connect anexternal standard capacitor, or connect an external oil cup to measure thedielectric loss of insulation oil, or connect measuring electrodes to measurethe dielectric loss of solid insulation material.

(5) Automaticallyrecognize 50Hz/60Hz power source;

(6) With Series orParallel methods of measurement;

(7) Automaticallyrecognize external HV power source with frequency between 40-70Hz, can be usedtogether with AC test transformer or AC resonant test system;

(8) 100 test resultsstorage facility, computer interface.
