How does corrosion affect the safety and reliability of power distribution equipment?

Abstract – Corrosion can severely impact the safety and reliability of power distribution equipment while imparting significant costs to the end user. This paper will discuss the root cause of corrosion, the monetary effect of early product failures and unplanned outages, and available solutions through equipment design and proper maintenance.

Is corrosion causing a power outage?

According to a study conducted by EPRI (Electric Power Research Institute of the US) more than half of all unplanned power outages are due to corrosion. This falls in line with several other studies which have shown that generally half of all failures within an industry segment tend to be corrosion related.

Why is corrosion prevention important for power plants?

As power plants look to increase effciencies and lower maintenance costs, corrosion prevention becomes critical. Fossil fuel plants tend to experience corrosion issues when they have buried storage tanks for fuel and underground piping systems.

What are some examples of corrosion in power distribution systems?

Power distribution systems not functioning as designed may result in significant safety or performance concerns. Fig. 1 Examples of common corrosion such as pipeline/bridge structures and bolts rusting and silver tarnishing. II. CORROSION BASICS Corrosion is the its environment, usually reaction of a metal with in a destructive manner.

What is a corrosion prevention strategy?

Corrosion Preventative Strategies: By creating a Corrosion Prevention Strategy, organizations are able to properly implement corrosion prevention technologies and strategies which will lead to overall cost-savings as well as implement design practices that increase reliability and safety, conserve materials and energy, and reduce costs.

How much does corrosion cost a power plant?

Others use nuclear power, however cleaner renewable sources such as hydroelectric, wind, and solar are increasing in recent years. The direct cost of corrosion is estimated to be $27.7 billion, Fig. 8. As power plants look to increase effciencies and lower maintenance costs, corrosion prevention becomes critical.
