InteliPro G59 Mains Protection Relay – ComAp

The world of mains protection is changing, with the introduction of EREC G99-1. G99-1 will replace G59-3.4 on the 27th April 2019. Learn more about this new recommendation from the ENA here.

The InteliPro G59 Mains Protection Relay is the ideal product for generators connected to the distribution network.

The InteliPro meets the strictest utility interconnection requirements, including G59-3.4 and G99-1 non-type tested and so can be used in wide ranges of distributed generation applications such as Photovoltaic, Wind, Fuel Cell, Bio Mass and Combined Heat and Power.

The relay has advanced communication capabilities, such as remote monitoring control via web browser, active SMS, email messaging and data/event logging. These make the InteliPro an excellent choice for remote controlled installation.

G59 3.4

Changes to G59 saw the implementation of G59 3.4 in July 2018. These updates affect all Non-Type Tested Generating Plants from 50Kw and above commissioned after 31st January 2018.

G59-3.4 has disallowed the future use of Vector Shift protection and provided new RoCoF requirements. Learn more about these changes here. 

 

G99-1

G99-1 is an important change to mains protection. When it comes into effect on 27th April 2019, it will replace the current G59-3.4. Equipment that is currently compliant with G99-1 can also be connected under G59-3.4 as it will meet the existing conditions. Learn more here about the changes.
