CATHODIC PROTECTION – TESTING AND COMMISSIONING
A) TEMPORARY CATHODIC PROTECTION SYSTEM
PSP of entire pipeline
Checking of Insulation joint.
B) PERMANENT IMPRESSED CURRENT CATHODIC PROTECTION SYSTEM:
Disconnection of TCP system
Energising the Transformer rectifier System after check up of completer system
Recording of Transformer rectifier parameter
Adjusting PSP on rectifier as per design.
PSP recording of entrie pipeline.
Recording an ode potential and output of each anode bed.
Due to cathodically protected foreign pipelines
Due to EHT crossing
Due to D.C. Traction
ICCP SYSTEM TESTING AND COMMISSIONING
All supplied main equipment / materials viz transformer – rectifier unit, anodes, and cables shall be tested at manufacturer’s works before despatch to site.
All equipments / system components shall be subject to pre-commissionng checks / tests / measurements, as required before, during and after their installation / erection/ construction as per normal practice.
Based on the results of the performance the output current of the T.R.Uni shall be adjusted to provide optimum level of pipe-to-soil potentials at various locations of pipelines.
