执行标准: IEC 61730-2:2004 & Ed.2"局部放电试验
BR-PV-PDT Partial Discharge Test System
Implementation of standards: IEC 61730-2:2004 & Ed.2, IEC 60664-1:2007, IEC 60243-1:1998
Capable of testing capacitance range: 6pF~250μF
Electric charge measurement range: 0.1~1000pC
Electric charge measurement precision: 0.1pC
Application AC voltage: AC0.01kV~5kVrms (Voltage change: automatic / manual)
Automatic voltage change model: 3 basic models
Voltage measurement accuracy: better than 5%
Apparatus
Calibrated charge measuring device or radio interference meter according to IEC 60664-1. If testing foils, the geometry of the electrodes shall be in conformance with IEC 60243-1 figure 1a. If testing a complete module, one electrode shall be connected to the short circuited module terminals, the earth electrode acc. to IEC 60243-1 figure 1a (bottom electrode) shall be connected to the frame and placed on the surface of the module (front or back sheet). The position of the electrode shall be chosen to represent critical points; a total number of 10 points shall be chosen.
Pass criteria
The solid insulation / module has passed the test if the mean value minus the standard deviation of the partial discharge extinction voltage is greater than 1,5 times the given maximum system voltage. When calculating the standard deviation the voltage step distance of the apparatus used shall be taken into account.
Note: Care should be taken to prevent undesired noises to occur during the test according to IEC 60664-1 annex D.3.
