Voltage surge simulation

The surge simulator type VSS 500N15.3 generates high voltage transients as required by IEC 60255-27 with a source impedance of 500 ohm for transient overvoltage tests on “Protection Relays”. The output voltage ranges up to 15 kV, divided into two voltage ranges (up to 6.6kV and up to 15kV).
The no-load waveshape corresponds to IEC-61180-1. For this kind of testing the IEC 60255-27 standard requires a fixed energy of 0.5 J at each test level.

VSS 500N15.3 – Voltage surge generator with constant pulse energy

The VSS 500N15.3 Surge tester generates high voltage transients as per requirements of IEC 61180-1 (specification of the waveshape) IEC 60255-27 to specifically perform transient overvoltage tests on “Protection Relays”. According to this standard the pulse energy is to be kept constantly at 0.5J at each test level hence a variety of pulseforming networks is implemented in order to obey this specification.
The output of the VSS 500N15.3 is devided into two ranges; the lower range covers the test up to 6.6 kV while the higher range supports testing between 6 kV and 15 kV.
Dealing with considerable high voltage and energy safety features such as interlock and warning lamp control self-evidently considered.
Peak voltage measurement as well as the detection of spark-overs are implemented to accomplish the documentation of the performed tests.
Pre-programmed Standard Test routines allow highest user convenience. Still the VSS 500N6 offers the Quick Start test routine where parameters can be changed on-line during the test. Fail inputs are offered as standard for DUT monitoring purposes.

Easy to operate

Front panel menu and function keys enable the user to program his test routines quickly and accurately. The cursor 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.
