Q20 Automatic Capacitance & Tan Delta Test System


Q30 Precision Capacitance & Tan Delta measuring test system is designed for the measurement of very low dielectric losses and impedances (Dissipation factor and Power Factor) of high voltage equipment, liquid and solid insulation. The instrument works on the principle of a combined bridge-vector meter and is capable o analysing capacitive and inductive loads.

The graphical user interface of Q30 is highly intuitive and focussed on the convenience of operator. Advanced software functionalities such as analysis of test result, comparison of parameters and report generation makes it an advanced diagnostic instrument.

The powerful Q30 software efficiently performs test at desired voltage level and records all relevant parameters, which are user selectable. Important information related to the device under test can be feeded into Q30 for analysis and report generation.
