SCR ELEKTRONIKS Impulse Voltage Tester are designed for interference test as per IEC 61180. Impulse Voltage Testers produce a Voltage Impulse of the required 1.2 / 50 microsecond waveform, meaning a high voltage pulse with 1.2 microseconds rise time and 50 microseconds fall time. The voltage level is settable from 0.5kV to 25kV (depending upon model).
While many devices are required to confirm to withstand this voltage impulse and current surge, we are outlining a few IEC standards that refer to this test – IEC 61000-4-5, IEC 60065, IEC 60335,IEC 60898-1, IEC-61008 IEC 60947-1 & IEC 60950-1/IS 13252-1.
The peak voltage can be adjusted by the user. The test sequence i.e. number of Pulses for Positive and Negative polarity, time between two subsequent impulses & so on can be programmed with the help of a dedicated PLC module. The entire sequence, for both positive and negative impulse is automatic. At the end of the test, the test results are displayed on LCD display. Output is provided for connecting an oscilloscope for displaying the Wave Form at the output Terminal. In case any flash over occurs, it is detected by a circuit which stops the test sequence, and PLC displays the number of cycles with polarities at which the failure has taken place. We have a PC based model available which can be used as an ’Automated Test Equipment’ in factory or lab.
Impulse voltage tests are recommended with the object to determine effect of voltage stress on insulation due to voltage pulses of short durations. An Impulse is a form of over voltage, which may occur in real-life scenarios such as a Lightening on an insulation, causing the formation of current path, thereby impairing the insulating property permanently. OR a voltage impulse on a line with an open MCB in it, might jump across the contact & cause a path due to an arc which in turn might damage part of your machinery. Therefore, the insulation must withstand voltage Impulses as defined in BS 61180 or UL 60950
The SCR Make Surge Current Testers are designed for interference test as per IEC 60065. Surge Tester is intended for testing of insulating materials, and for testing of particular components in mains operated electronic apparatus for household and telecommunication. This is tested with high voltage surges 10kV.
The Surge Testers will produce a current surge with the required wave-shape of 8 / 20 microsecond, meaning a high current surge with 8 microseconds rise time and 20 microseconds fall time.
SCR make Ring Wave Generator is designed for testing of Residual Current Circuit Breakers (RCCB) according to IS 12640 (Part 1) / IEC 61008-1 Clause No. 9.19.1
The generator comprises an electronically regulated high-voltage power supply, an energy storage capacitor, a high-voltage/ high-current switch, a pulse forming network and a Single-Board Computer with Touchscreen to measure, control and display the waveform.
CDN (Coupling and Decoupling Network) (Filter) for testing setup for ELCB compatible to ring wave generator (Single Phase).
