PD meter type PDM 201PDM 201 represents digital (in IEC 60270 terms) partial discharge measuring instrument.The instrument is designed for application, as in research laboratories, so in working conditions, at acceptance tests stands of industrial facilities.
Basic technical data and specifications of the instrument are shown in table:
PDM 201 instrument allows all GOST 20074 and IEC 60270 recommended PD characteristics measuring circuits to be realized:
Instrument takes real-time simultaneous measurements of all the quantities related to partial discharge pulses, recommended by standards:
Instrument provides real-time display image of different (at operator option) measurement oscillograms view, including 3D, as well as test procedures diagrams with measuring of PD characteristics. Instrument software (“PDScanner 2.0”) allows for operator to choose mode and range of PD quantities measurements in object, make calibration of measuring circuit (in manual or automatic mode), and also save measurements and calibration data in test report, automatically created by the instrument. During measuring operator can record to report any measurement point of time in the form of oscillogram with all PD quantities values attached. Noise, threshold, and positional filtering of the digital measuring signal, provided by the instrument, guarantee high-noise immunity of measurements, so it is not necessary to install the instrument in special, carefully shielded rooms: it is used successfully in conditions of electrical equipment manufacture. The instrument delivery set is shown in table:
At Customer option the instrument is manufactured in "3-phase" version, which provides simultaneous PD characteristics measuring in all three phases of test object. |
