Remote monitoring devices to monitor your complete cathodic protection system include: Rectifiers, anode, testpoints, drains, etc.
Also, they carry out specific cathodic protection functionality:
What is cathodic protection?
Cathodic protection is a way of protecting pipes from corrosion. In fact, this preventive measure supplies a direct current to steel pipes that run into soil or water. Due to the electric current on the steel pipes, there is a potential drop.
What is telemetry?
Telemetry, or remote control, is the remote monitoring of conduits with the aid of sensors. In fact, Withthegrid sensors are connected to an asset and periodically send encrypted measurement data to an online dashboard. In addition, our digital map shows which parts of the pipe are functioning properly and which ones need attention. Also, in the event of a malfunction, you are immediately notified. Moreover, the panel will then show what action needs to be taken. Once implemented, actions can be analyzed.
Measuring and monitoring cathodic protection with Withthegrid sensors:
Withthegrid sensors monitor cathodic protection on steel pipes. In fact, our sensors are connected to the rectifier and various measuring points along the pipe. For example, both the voltage ( DC + AC ) and the current (DC + AC) are measured (in accordance with NEN-EN 13509: 2003 ). Also, a coupon measurement is possible to measure the IR-Free (in accordance with ISO-NEN18086: 2015). Then, the data is then sent to a digital dashboard. In general, this allows transparency within the entire CP system. Additionally, one can switch the rectifier for the execution of off potential measurements or for doing work on the pipelines.
Which CP installations does the Withthegrid system work on?
Modbus connection rectifiers: For the Amstel rectifiers with a Modbus connection, a specific sensor is available (Amstel modbus sensor powered by Withthegrid). In fact, it ensures that settings in the rectifier can be adjusted remotely. Also, it enables precise and synchronous switching.
Other rectifiers: For instance, other rectifiers are read out and switched via an analog connection. In fact, accurate and synchronous switching is made possible thanks to an external Eaton relay.
CP – points: The Withthegrid sensors can lie in metal poles and round plastic poles.
AC / DC-drains: The Withthegrid sensors may also lie in drains.
