Standard Capacitors

HAEFELY / Tettex

Standard capacitors are indispensable instruments in every high voltage laboratory and test field where it occupies a wide range of important functions. From air-filled to SF₆-filled, Haefely’s range of nominal capacitors are specially built for high accuracy measurements. They can be used as a capacitance standard together with the 2823 High Precision Tan Delta Measuring Bridge, MIDAS 2881, or MIDAS micro 2883 to measure the dielectric dissipation factor (tan delta), as a reference capacitor for voltage measurements, or to measure the dielectric constant or capacitance of cables, insulators, transformer windings, etc.
