Wondering which Dairyland products you need for your application?  You are not alone!  Dairyland’s lineup of products offers a wide range of features and ratings to cover a diverse set of applications, and it can be confusing to identify what products you need.

Decouplers are commonly used to isolate cathodically protected structures from other grounded systems, enhancing the cathodic protection system’s performance. They also perform a function of safely grounding induced AC voltage, AC fault current and lightning. Over-Voltage Protectors provide the same DC isolation and protection from fault current and lightning but are not designed to address induced AC voltage.

This presentation explores:

• Dairyland’s vast selection of decouplers and over-voltage protectors
• How to choose the correct decoupler for your all your various applications
• How to properly size it based on the voltage thresholds, presence of steady state AC voltage, and AC fault currents.
