60-Day Record of Rectifier Operation for Impressed Current Cathodic Protection System

It is mandatory to report any significant variance to a corrosion expert so that necessary repairs and/or adjustments can be made. The app is easily accessible via smartphone and tablet and helps underground storage tank owners follow these regulations and requirements.

CP systems generally control the corrosion of metal surfaces by making it the cathode of an electrochemical cell. The metal that an owner/operator wants to protect can be connected to a metal vulnerable to corrosion, which acts as the anode. This anode then corrdes instead of the cathode. In this context, a rectifier converts an alternating current (AC) input to a DC output. It typically recudes the incoming AC voltage with a stepdown transformer and converts current to DC with a rectification section. The 60-Day Record of Rectifier Operation for Impressed Current Cathodic Protection System app allows a UST owner or inspector to record their rectifier's manufacturer, model, rated DC output, serial number, and "as designed" or "lastly recommended" rectifier output in volts and amps. Then, the inspector can record the date inspected (every 60 days), whether the rectifier is turned on, tap settings (coarse and fine), DC output (volts and amps), hour meter, and comments.
