Overview
Haefely's 2830/2831 is the result of extensive research and years of experience testing dielectric properties of liquid and solid insulating materials. It incorporates a fast and highly advanced procedure to measure capacitance, tangent delta (dissipation/power factor), resistivity, and relative permittivity of liquid or solid insulating materials. A simple one-time-connection system together with resistivity measurement according to pre-selected standards drastically reduces measuring time. The system consists of 2830, the measuring bridge and control unit, and 2831, the extension unit. This system is a complete replacement of the Tettex 2821 and 2822. The 2830 contains the controller and the measurement part of the system. The 2831 extension unit contains a standard capacitor, 2.5 kV AC & DC power supplies and a temperature control unit.Features
