Combination Wave Generator

Combination wave generator can be used to generate impulse of exponential shapes to perform high energy surge tests. The system can output combination wave (open circuit voltage 1.2/50μs & short circuit current 8/20μs).
With additional impulse modules, it can output 10/350μs and 8/20μs.

Additional Product Information

Features & Benefits
  1. Different impulse modules for up gradation in the future, easy for operation
  2. Automatic polarity switching
  3. Peak voltage and current monitoring
  4. Integrated large test cabinet with dimension of 40*40*30cm
  5. Open structure for expand waveforms
  6. Easy operation and maintenance
  7. Liquid insulation in the impulse capacitors is made of castor oil which offers optimal environmental compatibility (no PCBs). The impulse capacitors have very low inductance, high quality and long service life.
  8. Considerate safety measures
  9. Door safety interlock

1) The whole cabinet is grounded to earth.

2) Emergency stop button is equipped with magnetic materials and is removable on both sides according to the height of the operators.

3) One magnetic switch on the door of the test cabinet. When it is charging, it is impossible to open the door of the test cabinet. Unless the operator stops or pause the test, the door of the test cabinet can be opened.

4) Manual earthing rod and Automatic earthing system



Test Class II or Class III SPDs
