Standard Specification for Calibration of Partial Discharge Tester for Pulsed Current
1 Scope
This specification applies to the pulsed current method, measuring the frequency range of 10kHz ~ 500kHz between the partial discharge test
Calibration of the test instrument.
2 reference file
This specification refers to the following documents.
Partial discharge measurement GB/T 7354-2003
For dated references, only the dated edition applies to this specification; references that are not dated
, The latest version (including all modifications) applies to this specification.
3 terms and units of measurement
GB/T 7354-2003 Definitions and the following terms and definitions apply to this specification.
3.1 pulsed current method partial discharge tester pulsecurrentmethodbasedpartialdischargetester
Through the acquisition of pulse current signal to achieve electrical equipment, local discharge measurement of special equipment.
3.2 Impulse response of partial discharge tester pulseresponseofpartialdischargetester
When the measuring circuit of the partial discharge tester injects the calibration pulse signal, its corresponding pulse output is displayed.
3.3 Calibration pulse generator calibratedpulsegenerator
By the voltage amplitude of U0 pulse voltage generator and the injection capacitor C0 with the composition, can produce a known charge amount q0
Of the pulse current generator.
3.4 apparent charge amount apparent charge [GB/T 7354-2003, definition 3.3.1]
The apparent charge is equal to the specified test circuit, if in a very short period of time between the two sides of the sample
The amount of readings on the measuring instrument is the same as that of the PD circuit itself. The apparent charge is usually used in the library
(pC).
3.5 pulse resolution time pulseresolutiontime
[GB/T 7354-2003, definition 3.9.5]
The shortest time between successive pulses of the same duration and the same amount of charge and the same amount of charge
Interval, the amplitude of the impulse response in this time interval is not greater than 10% of the amplitude of a single pulse.
The pulse resolution time is generally inversely proportional to the bandwidth Δf of the measurement system and is also a measure of the system.
The ability to characterize.
3.6 pulse repetition rate pulserepetitionrate
[GB/T 7354-2003, definition 3.3.2]
The ratio of the total number of localized pulses recorded in the selected time interval to the time interval.
Note. Actually only consider the pulse above the specified amplitude or within the specified amplitude range.
3.7 Measurement sensitivity detectablesensitivity
