With an active cathodic corrosion protection the installation is permanently protected against the electrochemical process of corrosion. For that matter a grid supplied rectifier is inserted between the installation (e.g. a pipeline) and an anode that serves as earth electrode. By connecting two or three PLPro units in parallel the overall current can be elevated up to 80 respectively 120 A.
AC discharge current: 40 or 80 A
Several PLPro devices can be connected in parallel to raise the total discharge current
Maintenance-free, without liquids
No disturbance of search signals
Monitoring of discharge current with integrated current transformer possible
Integrated lightning and surge current protection up to 100 kA (10/350 µs)
Safety switch for discharging the capacitors
