Description

The surge generator type VSS 500N10.3 is specifically designed to generate high voltage transients as required by IEC/EN 61730-2 for safety testing of photo voltaic panels.

The specified waveshape of 1.2/50us must be generated and maintained as specified across a broad range of capacitance the PV's do represent and as such the generator needs to be based on different pulse shaping networks to cope with the variable capacitive load of the panels depending on their size and design.

As per IEC/EN 61730-1/2 requirements for surge testing of photovoltaic panels these shall be wrapped with copper foil. This leads to comparatively high capacitance values of several tenth of nanofarad (typically values between approx. 30 and 180nF are seen). This capacitance is switched in parallel to the output of the generator. The required waveform of 1.2/50us needs to be maintained within the specified tolerance for the entire load range. To cope with these requirements a dedicated impulse voltage generator is required.

The EM TEST VSS 500N10.3 has been designed to cover the full range of capacitives load photovoltaic panels may represent offering 7 different load ranges. Each load range is based on a separate pulse forming network to comply with the tolerances given in the standard.

The VSS 500N10.3 offers manual operation as well as remote control operation via software.
Pre-programmed test routines are offered for the 7 different load ranges as well as the Quick Start and the User Test routines for manual operation via front panel. USB and GPIB interfaces are implemented for software control.
