Solid State Decoupler
Retrofit Systems
Solid-state decoupler are a type of AC interference protection product which integrates embedded discharge and surge protector.
They are mainly used in long distance buried pipeline engineering.
Description:
Solid-state decouplers are a type of AC interference protection product which integrates embedded discharge and surge protector.
It is mainly used in long distance buried pipeline engineering.
Near the pipeline of high voltage transmission line iron tower/communications tower, and grounding system, the parallel transmission lines and pipeline within the period of the public corridor, in the pipeline, and transmission lines cross location and electrified railway parallel section, install to couplers are effectively reduce the DC and AC stray current or lightning current’s influence on the buried pipeline, Enhance the stability of pipeline cathodic protection potential measurement.
Application Field:
- Decoupling of pipeline potential gradient pad (ground pad).
- Over voltage protection for AC failure, lightning and switching transient processes (such as insulated joints and flanges).
- For safety, used for decoupling between different metals, which in some cases have AC coupling.
- AC grounding and DC isolation of electrical equipment in cathodic protection systems.
- Reducing the AC induced voltage
Features:
Installation of couplers effectively reduces the DC and AC stray current or lightning current’s influence on the buried pipeline, enhancing the stability of pipeline cathodic protection potential measurement.
