Rustrol® Polarization Cell Systems
The Rustrol® Polarization Cell Systems are rated for up to 100 kA AC fault current capacities, in 5 kA increments. Each Cell System is capable of blocking 1.7 volts DC. A full product line is available to meet the challenge of all applications.
Rustrol® Polarization Cell Systems are typically specified for earthing applications where major power disturbances are not the primary exposure. Some examples include: decoupling a structure from ground rods, casings or other isolated earths. AC power pulses, lightning surges, stray DC interference and induced AC voltages are all standard applications for the Rustrol® Polarization Cell. All Cells are rated to safely pass ½ second (30 cycle) AC fault current, with a terminal potential rise across the Cell, not exceeding 15 volts rms at 20°C.
Rustrol® Polarization Cells optimize the safety of personnel and equipment. Rustrol® Polarization Cell Systems are utilized to decouple massive metallic structures where electrical disturbances, caused by AC fault currents, present high-risk exposure. Typically, Rustrol® Polarization Cell Systems are specified for direct connections across isolation flange assemblies; between pipe-type cable systems and station ground; or between cathodically protected structures and the electrical grounding system neutral.
