JYH C CT PT analyzer,full-featured, can not only satisfy the test requirements of various CTs (include TP class), such as the excitation characteristics (i.e., volt-ampere characteristics), ratio, polarity, secondary winding resistance, secondary burden, ratio error and phase displacement, but can also be used for the tests of various PTs, including excitation characteristics of the electromagnetic unit, ratio, polarity, secondary winding resistance, ratio error and phase displacement.
Function Introduction
•Automatically give CT, VT parameters,
including knee point voltage / current, 10% error curve, the accuracy limit
factor (ALF), instrument security factor (FS), the second time constant (Ts),
remanence coefficient (Kr), saturated and unsaturated inductance etc.
•Test meet IEC60044 standards.
•Based on advanced principle of
low-frequency test method that can meet the CT test on knee voltage up to 60KV.
•Friendly interface beautiful, all English
graphic interface
•The instrument can store 1000 groups of
test data that won’t be lost when power off. After test ended, the data can be
copied to PC by USB disk for analysis and being transformed into WORD report.
•Test is simple and convenient, one-click
can complete tests of CT secondary resistance, excitation, ratio and polarity.
