2003'  泊睿成立

2006'  偶然承接了國內光伏行業*組件紫外預處理試驗機, 自此躋身光伏行業...

2007'  面向光伏領域全面技術轉型...

2008'  大發展時期, *研發或*商品化了大陸地區*冰雹試驗機、機械載荷試驗機、組件穩態模擬器...同年研發出或許是國內光伏行業*(中國臺灣可能同年)引出端強度試驗機、導線管彎曲試驗機、孔口蓋敲擊試驗機、抗劃傷(切割)試驗機、UL推擠試驗機...

2009'  行業一片"冬天"、"洗牌"聲中, 泊睿貴在堅持...

2010'  第二輪大發展時期...

2011'  完善了組件及光伏方陣戶外測試系統及穩態模擬器的全部測試項目, 研發出全自動UL熱斑耐久試驗機、組件鹽霧試驗室、接線盒標識耐久性試驗機、組件PID電勢差誘導降解試驗系統...

2012'  光伏殤年,泊睿與業界共渡時艱…

2013'  尊嚴來自實力…

Test object:

TPT (IEC 61730:2004)

TPT into silicone oil during test

IEC60664-1:2007

 

Module (IEC 61730 Ed.2)

IEC 60243-1 figure 1a (see right)

 

Electrode diameter: 25cm

Chassis diameter: 75cm

 

    
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.
