3 OVERVIEW Corrosion control by Cathodic Protection is a highly specialized field, which is more an art rather, then science and one of the widely used tools and control of electrochemically corrosion. It is defined reduction or elimination of corrosion by making the metal a cathode by means of impressed direct current or attachment to a sacrificial anode (magnesium, aluminium, or zinc). In design, various size and design of cathodic protection transformer rectifier cannot be avoid since design of plant and environment very special for each case. Updating Technology such as PLC/DCS which applied to plant design also much be considered to cathodic protection transformer rectifier with concept to minimized maintenance. FAYTEK come with all about concept and making cathodic protection transformer rectifier with wide range. Manual Tap Setting Manual Smooth Adjustable Setting Auto Potential with Communication Unit Dry Type (Diode/SCR and Switch Mode) Oil Type FAYTEK in plant operation supported by Transformer manufacturer specialist Metal workshop fabrication Metal cleaning and pointing shop complete with oven room Assembly workshop complete with testing equipment. Electrical test performance at cathodic protection transformer rectifier shall be as following: - AC Volt Input - AC Amperes Input - Apparent Watts Input - True Watts Input - Power Factor - DC Volt Inputs - DC Amperes Input - DC Watts Input - Conversion Efficiency - Dielectric Strength - Transformer Insulation Primary Winding - Transformer Insulation Secondary Winding - Stack AC and DC to Ground - Ripple Voltage at Full Output FAYTEK supported with experience professional teams research and development teams, constantly updating production quality, which in the end of result will be, keep customer in satisfied and convenience FAYTEK always keep the opinion that with our products customer always getting best performance from their protection system 3

7 RECTIFIERS CONTROLLER RC-Series Fig5. Controller Board RC-Series for Auto potential CPTR A microprocessor based cathodic protection rectifier controller, only six keypads for all operation, 16 X 2 characters of LCD, and so easy for use The RC-Series can operate in CONSTANT CURRENT CONSTANT VOLTAGE AUTO POTENTIAL The RC Series has four different references input. In auto potential mode, it controls on the lowest reference to structure Potential measured and can control on the average or instant OFF potential. The RC-Series trough RS-485 have capability to communication with PC under windows program, each other s unit and become master or Slave. This advantage will be covered costumer demand for control all RC-Series at field from 1 (one) unit only such as current interrupter.
