BR-PV-WLC Wet Leakage Current Tester with Spray System
Implementation of standards:
IEC 61215:2005 & Ed.3, IEC 61646:2008, IEC 61730-2:2004, UL 1703:2008, VDE 0126-5:2008, VDE 0126-3:2009...
System composition:
Basic framework: Insulating water slot air-conditioning (or constant temperature circulating cistern) detergent conductivity detector surface tension determine instrument spray frame program-controlled insulation voltage tester with Light-Screen safety protection system
Insulation voltage test explains:
IEC 61215/61646/61730, were not given insulation voltage test pass/fail discriminant basis, we quoted UL 1703 "Dielectric Withstand Test" by - as Test discriminant basis, namely: Compression test stage no more than 0.05 mA leakage current. In addition, the program, should not be greater than pressor 500V/s, module belong to capacitive load, we find that moment caused by leakage current charging electric current exceeds.
The insulation and spacings between live parts and accessible conductive parts and between live parts and exposed nonconductivesur faces shall withstand the application of a DC test voltage equal to two times the system voltage plus 1000V without the leakage current between these two points exceeding 50μA DC. The voltage is to be applied in both polarities.
