Design considerations for system-level ESD circuit protection
ESD protection Figure 4 shows the characteristics of a TVS diode''s current versus voltage. Even though a TVS is a simple structure, several important parameters should be considered in the design of system-level ESD protection. These include breakdown voltage, V BR; dynamic resistance, R DYN; clamp-ing voltage, V CL; and capacitance ...
Get PriceSurge Protection for AC Rotating Machines
Protective capacitors offer surge protection for AC generators, synchronous condensers and large motors. Surge capacitors protect the winding insulation by reducing the steepness of wave fronts applied to or reflected within the machine windings. Dielektrol™ is the GE non-PCB power capacitor dielectric fluid developed
