PV Panel testing – 1.2/50us Surge generator as per IEC/EN 61730

The surge generator type vsurge NX20 is specifically designed to generate high voltage transients as required by IEC/EN 61730-2: Ed 2.0 (2016) 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. Such 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.

vsurge NX20 – Pulse voltage generator for photovoltaic panels

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. 20 nF and 170 nF 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 vsurge NX20 has been designed to cover the full range of capacitive load photovoltaic panels may represent offering 11 different load ranges. Each load range is based on a separate pulseforming network to comply with the tolerances given in the standard.

Same as all EM TEST equipment the vsurge NX20 offers manual operation as well as remote control operation via software. The generator detects automatically the manual selected PV-panel capacity range as well as the polarity for all tests. Opto Link with USB at the computer and ethernet interfaces are implemented for software control.

Easy to operate

Front panel menu and function keys enable the user to program his test routines quickly and accurately. The touch screen allows fast control of all test parameters of the programmed routine, thus test procedures are simplified and confidence is generated that every step is carried out correctly.

iec.control Software for control and documentation

Outstanding user convenience, clearly structured windows and operation features, EM TEST’s comprehensive standards library along with the flexibility to easily generate user specific test sequences are the main features of iec.control software. The software will be automatically configured in accordance with the connected EM TEST generators. Extensive reporting capabilities help the user to create test reports that meet international requirements.
The iec.control is supported by Windows 7, Windows 8 and Windows 10. Remote control is achieved either via Ethernet or optical interface with USB connector at the PC side.
The iec.control supports various interfaces for the communication to external measuring devices.
