FC-2GB Lightning Protection Components Tester is a portable instrument for measuring DC parameters of over-voltage protection components. It is intended for verification, routine testing and batch/continuous testing of ZnO arresters, cermet two- and three-electrode discharge tubes, vacuum lightning tubes and other over-voltage protection components.
Applications- Testing zinc oxide arresters (varistors, VDR).
- Testing cermet 2- and 3-electrode discharge tubes and vacuum lightning tubes.
- Verification and production-line testing of other over-voltage protection devices.
Key features- Performs DC parameter testing: voltage-dependent resistance (varistor), DC breakdown voltage of discharge tubes and leakage current measurements.
- Can operate as a regulated DC supply and as a constant-current source for specific test conditions.
- HV short-circuit protection and over-current protection; high-voltage preset and measurement range adjustment; HV self-discharge time < 0.5 s.
- Built-in self-calibration to improve measurement reliability.
- LCD display with high precision and reliable readout.
- Pre-set measurement range with audible alarm when results exceed the range.
- Continuous measurement mode for mass testing and production inspection.
- Simple front-panel operation; lightweight and portable design.
