ACL no Leak

Solid state polarization cells or SSD is an AC discharge devices, used to mitigate pipeline AC voltages resulting from induction from overhead power lines sharing the same right-of-way. A main purpose of the AC discharge devices is to protect operating personnel from hazardous touch voltages.

Balanced AC discharge

An increasingly important task for the AC discharge device is to inhibit AC influenced corrosion by lowering the pipe to soil AC voltage. CP experts throughout have reached agreement that excessive cathodic protection combined with AC voltage is a non-tolerated mixture, likely to cause accelerated AC corrosion. The AC discharge devise has been designed and developed for the purpose of being completely neutral to the DC thus to maintain the rectifier in full control of the cathodic protection level. Unlike other known solid state polarization cells it does not produce additional cathodic polarization by rectifying the AC voltage.
