Integrated protection solution for generators operating in parallel to mains applications. Configurable to suit customer requirements.Find out more
The ComAp MainsPro is a G59 3.4 and G99-1 non-type tested protection relay for mains-to-parallel applications, including generator sets, cogeneration, micro turbines or renewable energy sources such as photovoltaic plants, wind turbines and hydro-electric.
It provides adjustable voltage, frequency and loss of mains protections to safeguard both the distribution network and the generators.
If you are generating power in parallel to the mains, you will need ‘loss of mains’ protection. This is essential to avoid supplying your electricity into an islanded grid, which may lead to possible equipment damage or safety issues.
With MainsPro, no special knowledge is needed for installation and also no additional units are required. This makes it the ideal solution for personnel who are not specifically trained. The unit is designed to fully comply with Utilities’ connection requirements and statutory codes, offering a high level of protection and safety when working in parallel to the mains.
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 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.
There are good reasons why the MainsPro G59 relay has been and remains the market-leading mains protection relay:
Advanced communication, display and logging features are also available with the ComAp InteliPro.
