Cathodic protection remote control and monitoring systems

In order to ensure the proper functioning of cathodic protection systems, it is always necessary to perform periodic measurements of various system parameters at regular intervals. Considering the geographical area and climatic diversity of different regions of the country and the passage of oil, gas, etc. transmission lines in mountainous, desert or forest areas and the requirement to go to the cathode protection stations to measure the values, we always face special problems and spend a lot of money. Is. By using remote control and monitoring systems, it is possible to constantly monitor the performance of the cathodic protection system without being on site and ensure its correct operation. With the use of these systems, the problems and costs of periodic inspection for registration, control of quantities and personnel costs are significantly reduced. This technology allows the controller to control and examine several different cathodic protection stations from one place at the same time and quickly discover and fix system issues and problems. With years of experience in designing, manufacturing and implementing all kinds of cathodic protection systems, Brena Electronics offers the possibility of using CPRM systems on all kinds of cathodic protection systems.

Various parameters of the rectifier transformer and cathodic protection system can be measured and transferred to the control center. The monitoring system can be installed on different types of rectifier transformers regardless of the type of device and its manufacturing company and without any restrictions.

Some of the parameters that can be measured and monitored are:

Vac: rectifier transformer input voltage (0-500 volts)
Iac: the input current of the rectifier transformer (0-300 amps)
Vdc: rectifier transformer output voltage (0-300 volts)
Idc: output current of the rectifier transformer (0-300 amps)
Vref: the potential of the protected equipment compared to the reference electrode (0-5 V)
Oil Temp.: Oil temperature
Oil Level: announcement of a decrease in the oil level from the predicted minimum

Remote control is possible on devices that are equipped with a remote monitoring system. This is because control without monitoring tools can cause risks to the system. Also, after the changes in the control parameters, a feedback from the system is necessary and necessary to inform the user of the new situation. What can be controlled as the main parameters of the rectifier transformer are as follows:

Disconnect and connect the system remotely
The ability to control and adjust the output current or adjust the output voltage of the rectifier transformer
The ability to adjust the reference voltage of half batteries and as a result intelligent control of the voltage and output current of the rectifier transformer
General advantages of remote monitoring and control system

Control, measurement and storage of transformer parameters, rectifiers and potentials measured by reference electrodes and comparing them with each other
Automatic adjustment of the current and voltage of the rectifier transformer
Prevention of human errors
Save time and money by eliminating periodic visits
The possibility of disconnecting multiple rectifier transformers at the same time
The possibility of displaying the geographical location of the stations on the map by GPS / GPRS hardware
Remote monitoring systems have the possibility of adding custom features such as: measuring the current of anodes separately and other features.
Software capabilities

Creation of full identification of cathodic protection stations
Notification of a general failure in the cathodic protection system
