CATHODIC PROJECT AUTOMATION :

Experience of PYRAMID in Oil & Gas Sector

Cathodic Protection SCADA on Wireless Network.

GSM Based Remote Monitoring of Transformer Rectifier Parameters used for Cathodic protection of Oil / Gas pipeline.

Monitoring of PSP, TR Voltage, TR Current and TR status of multiple TR units.

Allen bradley PLC with GSM Modem were installed at each locations.

Data collected on SCADA Software on SMS through GSM network.

The alarms are also transmitted to user defined mobiles.

Customer can call for data on his cell for each site as per requirement.

Cathodic Protection Rectifiers areAC-powered electrical equipment that provide direct current for impressed current cathodic protection systems. Rectifier units are often custom manufactured and equipped with a variety of features, including oil cooling, automatic output adjustment, various types of electrical enclosures, remote monitoring, remote output adjustment, an AC electrical outlet, selectable AC input setting, three phase AC input.
