Which is the best method for Cathodic protection. Sacrificing anode method or Impressed current method?
When reliability is concerned then ICCP method is superior but when overhead cost incurred in installation and maintenance is concerned then sacrificing anode method is better than ICCP method.

What is the meaning ampere protection?
Amperes refer to the current in an electrical circuit. Ampere protection is rarely used but it refers to current protection. Typically this will relate to protection against over current events with fuses or circuit breakers.
If alternating current is impressed on one coil what will be the frequency of the induced voltage in another coil with which it is coupled?
Same frequency as that of primary coil
What is the protection of over current to a diode?
we use fuse only .thanks
What is residual earth fault protection?
Earth fault protection is protection based on ground, or zero sequence current. If current is coming up from the ground (or going down to the ground), this protection should operate. Residual usually refers to 3*I0, which is the same as the ground current, and is the vector sum of the current in all three phases. This can be measured by connected all three phase CTs in wye, and placing a single phase overcurrent relay in the wye path to ground.
Why field effect transistor is called voltage controlled device?
A FET is just a material either N or P whereby a restriction is applied by a field volts impressed on the material as restricting the current flow or allow the current flow
How in industries do they stop metals corroding?
Good design Proper material selection coatings including metal coatings and paints Impressed Current Cathodic Protection Sacrificial Anode Cathodic Protection Anodic Protection Combinations - especially use of CP and coatings
KKS Power Plant Classification System for Cathodic Protection?
The KKS system is a standardized system for the classification of technical equipment in power plants. It does not specifically address cathodic protection systems. Cathodic protection systems are typically classified based on their method (e.g., impressed current or sacrificial anode) and location within the power plant.
15km pipeline is corrosion protected with Impressed Current cathodic protection at both end of pipeline 10metres of pipe is above ground. Will the CP system work on this above ground pipe?
Yes it will
How do electrons flow in cathodic protection?
In cathodic protection systems, electrons flow from a more active metal (anode) through an external circuit to the structure being protected (cathode), providing a protective current that helps prevent corrosion. This flow of electrons results in the cathodic polarization of the structure, thereby reducing the likelihood of corrosion.
What are the methods to protect iron from rusting?
Cathodic protection - attach a piece of zinc Cathodic protection - pass electric current through it - take care this is an industrial method only for protecting pipelines etc. Galvanizing Painting Wax/oil/grease
What three elements prevent corrosion?
Use of corrosion-resistant materials, such as stainless steel or aluminum. Application of protective coatings, like paint or enamel. Implementing cathodic protection methods, such as using sacrificial anodes or impressed current systems.
What is cathodic protectin survey?
Cathodic protection survey is a method used to assess the effectiveness of cathodic protection systems on buried or submerged metal structures like pipelines or storage tanks. It involves measurements of electrical potentials, current flow, and other relevant parameters to ensure that adequate protection is being provided to prevent corrosion and extend the lifespan of the structure. The survey results help in identifying any issues or areas that may require maintenance or improvements in the cathodic protection system.
Does voltage flow across a circuit or is it impressed across a circuit?
Voltage is impressed across a circuit. Current flows through a circuit.
How does voltage drop related to impressed emf?
Voltage drop is resultant of IR ie current and the line resistance, not dependent on impressed emf
What is the meaning ampere protection?
Amperes refer to the current in an electrical circuit. Ampere protection is rarely used but it refers to current protection. Typically this will relate to protection against over current events with fuses or circuit breakers.
What is cathodic inhibition?
A cathodic inhibitor is a type of corrosion inhibitor, a chemical compound that, when added to a fluid or gas, decreases the corrosion rate of a metal or an alloy. An example of a cathodic inhibitor is zinc oxide, which retards the corrosion by inhibiting the reduction of water to hydrogen gas. As every oxidation requires a reduction to occur at the same time it slows the oxidation of the metal. As an alternative to the reduction of water to form hydrogen, oxygen or nitrate can be reduced.
What the three types of over current protection relay and describe the principles of operation?
