SP type impulse current test systems can generate 8/20μs or 10/350μs impulse current waveforms. The systems can be used to test SPD, lightning rod and other lightning protection devices.
 
Features and Benefits;
Easy operation with the automatic control based on PLC module;Reliable and precise triggering unit by pulse amplifier;Automatical polarity change;Liquid insulation in the impulse capacitors is made of castor oil which offers optimal environmental compatibility (no PCB's). The impulse capacitors have very low inductance, high quality and long service life.Protective earthing system, earthing rod and emergency button, gate interlock for personnel and equipment safety;  Wave shaping resistors are designed for low inductance and connected with handy plug;Stable and precise communication between the measuring system and control system;Easy operation with the console based on Japan Mitsubishi PLC module, touch screen panel and computer screen. Optical-fiber is also used for high reliability;With Pearson brand current monitor made in USA to measure the current peak and Tektronix oscilloscope to record the waveforms;
