Application

The C type impulse current test systems with crowbar are sophisticatedly designed to generate impulse current of exponential shapes. The system can be designed in various ways for meeting customers’ requirements. The test system is applicable in testing of SPD, lightning protection components (MOV or air gap), lightning rod and aircraft device.
