배관에 방식을 위한 방식전류가 방식이 필요하지 않는 구조물로 유출되어 방식기능이 저하되는 것을 방지하고,
방식전위의 제한과 절연조인트를 AC 이상 전압, 뇌격 등으로부터 보호하기 위하여 사용된다.





1) 방식대상의 방식이 필요하지 않는 접지나 구조물등에 방식전류가 유출되지 않도록 차단하는 역할을 한다.
2) 배관에 AC 유기전압을 제거하여 AC로 인한 간섭을 최소로 한다.
3) 방식대상과 비방식과의 전기적으로 절연시 이상전압, 낙뢰 등으로 인한 절연부위를 보호하는 역할을 한다.


The uniquely designed Cathodic Isolator developed by Rustrol Systems, effectively confines the current needed for cathodic protection, while providing a safe grounding path during all types of electrical disturbances.
 
PROVEN CATHODIC PROTECTION.

Cathodic protection, proven by decades of service in a variety of applications, prevents corrosion of buried or submerged metallic structures.
Cathodic protection is most efficiently and uniformly applied when the primary structure is electrically isolated - i.e., all metallic/electrical contacts with foreign metallic structures are eliminated.
Electrical isolation provides three major benefits:

* Restriction of the required protective current to the surface of the primary structure to produce a uniform polarized level of protection
* Minimization of stray DC current interference
* Prevention of galvanic current between metallic structures.




SAFE CATHODIC ISOLATION.

Cathodic isolation is a superior form of electrical isolation. Cathodic isolation maintains stringent electrical grounding requirements and confines the protective current at the surface of the primary structure. The result is highly effective, uniform protection against corrosion.
The Rustrol Cathodic Isolator meets safety standards for effective grounding within the National Electrical Code, and conforms to the need for safe operation practices accepted worldwide, i.e., not to exceed the 15 volt rms(caution) potential most often stipulated by design.
The Cathodic Isolator provides all of the advantages of electrical isolation necessary for Cathodic Protection by blocking the protective current at the electrical isolating device - such as across a pipeline isolating flange. As soon as the potential across the isolating flange exceeds the pre-set voltage threshold, the Rustrol Cathodic Isolator responds instantly.

VERSATILE PROTECTION

The Cathodic Isolator protects personnel and equipment during all types of electrical disturbances by providing an effective grounding path which instantly conducts:
* AC fault currents
* Lightning
* AC induction
* Power switching surge currents.
The Cathodic Isolator is indispensable for safe electrical isolation - to assure unprecedented protection of your personnel and equipment.

APPLICATIONS FOR COST-EFFECTIVE OPERATION.

Along with performing a key role in safe and effective corrosion control, the Rustrol Cathodic Isolator also serves to reduce both the capital and maintenance costs of cathodic protection systems.
Cost-effective applications include:
* AC fault-current protection across isolating flanges and other devices
* mitigation of induced AC on pipelines and other structures
* lightning protection for equipment, including cathodic-protection rectifier systems
* de-coupling of the primary structure (e.g., fueling facility, pipe-type cable systems, etc.)from contact with the electrical utilities grounding network.
And these are just a few typical applications for the Rustrol Cathodic Isolator Other possibilities are limited only by one's imagination.
