Our Cathodic Protection Equipment is further thoroughly tested on varied parameters before its delivery to assure complete satisfaction to the clients. Product Features And Benefits :

• The operation of the unit in this mode will be fully automatic and will be controlled by the reference electrode feedback. The unit will automatically maintain reference voltage or pipe to soil potential (P.S.P.) within 10mV of the set value under all conditions. The controller will maintain the structure protected to set PSP value under input supply variation, load current variation and external Changes. Reference selector logic selects the lowest (least protected) reference signal and maintains the protection level.
• Natural Air Cooled or Oil cooled Indoor or Outdoor, Wall mounted or Base mounted.
• AC Operated, DC Operated, AC/DC Operated and Solar Power Operated.
• Units are designed to work under severe environmental conditions with temperature range up to 55 C ambient & protection class upto IP55 / IP56 & IP65.
• All transformers are designed to give low losses and high efficiencies. The core material is high grade, high permeability and low loss CRGO silicon steel. The coils are wound with high conductivity, annealed, insulated electrolytic copper conductors. The insulation material used is of high standard to suit Class F grade. The Transformers manufactured and tested as per IEC76, BS 171 standards.
• Rectifiers are based on international quality diodes and Silicon Controlled Rectifiers. Rectifier circuits have different circuit topology based on customer need, specification and efficiency. Single Phase Bridge is used up to 5KW output and above that three Phase Bridge or hexa-phase with inter phase transformer scheme is used for higher efficiency.
• Rectifiers are designed and tested as per IEC 146 standards.

Generally Following Protection Is Provided :

• Fast acting electronic over current limit & short circuit protection for output.
• MCB and / or HRC fuses in AC input, DC output for short circuit protection, overload protection & ON/OFF operation.
• Glass cartridge fuses in the live line of all lamps & in the auxiliary power lines to control circuit.

AC-DC Operated Units :

• Input Supply :
  • Single Phase or Three Phase as per customer specification
  • 24V, 36V, 48 V DC Battery Supply as per customer/Specification Requirements.
• Outputs : Standard Ratings are
  • DC Volts : 12, 25, 50 V
  • DC Amp : 5, 10, 25, 50 A

Additional Protections Are Provided As Per Customer Specifications Following One Or More Modes Of Controls Are Provided :

• The DC output voltage of the TRU in this mode is controlled in 24 symmetrical steps by means of a separate autotransformer with coarse & fine tapping. Autotransformer can have steps of 16, 24 or 64 as per customer specification.
• The DC output voltage of the TRU in this mode is controlled by stepless separate autotransformer connected in primary of main transformer.
• In this mode, the unit can be operated in either constant voltage or constant current mode. In constant voltage mode the DC output voltage will be adjustable from 0 to rated value in stepless manner by means of a voltage setter potentiometer. DC Voltage regulation will be better than 0.5%. The controller will maintain constant voltage at set value under input supply variation and load current variation to keep the structure protected.
• In constant current mode the DC output current will be adjustable from 0 to rated value in stepless manner by means of a current setter potentiometer. DC Current regulation will be better than 1%. The controller will keep current limited at set value under input supply variation and load current variation to avoid excessive current to the structure.

Salient Features :
