Operation and Maintenance of Cathodic Protection in India

Operation and Maintenance of Cathodic Protection as per Standards and Statutory Requirement for a range of sectors, including oil and petrochemical and industrial structure etc.
Schedule of monitoring and maintenance as per standards and statutory requirement
Recommended value of CP monitoring parameters and troubleshooting
Standard Operating Proceduresr
Monitoring & Maintenance of TRU/CPPSM
SCADA connection: Parameters transmitted are DC output voltage, DC output current, Selected reference cell potential, under-protection and over-protection, reference cell failure. To check transducers and compare data with field measurementr
Non-SCADA connection: Fortnightly monitoring of DC output voltage, DC output current, reference cell potential, under-protection and over-protection, reference cell failurer
The minimum potential is set at -0.85 V and maximum potential at -1.2 V both OFF. OFF potential through reference cell at drain point should be maximum - 1.2 V and at midpoint minimum - 0.85 V
Individual reference cell can be put as a controlling electrode to match reference cell potential with a target potentialr
Rectifier is operated on constant potential mode or constant current mode depending upon variation in potential readings.
