Partial discharge measuring systems

Partial discharge measuring systems

Partial discharge (PD) is a electrical discharge that only partially overbridges the insulation between conductors. Generally PD appear as pulses of duration of much less than 1µs.   The significance of PD in the lifetime of insulations has long been recognised. Every discharge event causes a deterioration of the material by the energy impact of high energy electrons and causing chemical transformations of many kinds.     PD-4 Professional partial discharge measuring instrument PD-5 Industry partial discharge measuring instrument Battery Calibrator Calibration standard according IEC 60270 -2000 PD-MUX x-channel PD multiplexer Capacitors Presco AG provides different series of: coupling-, standard air-, solid state- and compressed gas standard capacitors for different applications in high precision high voltage measurements.
