Integrated protection solution for generators operating in parallel to mains applications, particularly suitable for remote applications.Find out more
The ComAp MainsPro is a 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.
Please note that as of April 27th 2019, for sites connected after February 2018, connections using G59-3.4 only is no longer acceptable. All connections must be done using G99.
For sites connected before February 2018, they must be connected using the G59-3.4 standard. Learn more about retrospective upgrades and the National Grid’s Accelerated Loss of Mains Change Programme here.
The MainsPro relay is fully compliant with both G59-3.4 and G99.
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.
G99-1 is an important change to mains protection. Coming into force on 27th April 2019, it replaces the current G59-3.4. Sites commissioned before February 2018, that are currently compliant with G59-3.4 will need to be upgraded to G99. The ComAp MainsPro and InteliPro are fully compliant with the G99 legislation. Learn more here about the changes.
There are good reasons why the MainsPro relay has been and remains the market-leading mains protection relay:
Advanced communication, display and logging features are also available with the ComAp InteliPro.
