The G59 relay is designed to cause the connected circuit breaker to open if any of the above tests go outside of the programmed limits, for protection purposes. Since its launch in the mid-1990''s, T&R Test Equipment''s DVS3 Test Set has been the go to instrument for anyone testing to G59 regulations.
The G59 mains protection relay device looks at the stability and quality of mains'' electricity is programmed to strict parameters dictated by the DNO, typically including voltage, frequency, ROCOF (rate of change), phase angle etc. If the parameters are breached then the relay will cause a protective device, such as an MCCB or other circuit breaker to open, instantly
These regulations are commonly known as the ''G59'' requirements, and would apply to Combined Heat & Power (CHP) units, and Generators being used for peak-lopping, or grid parallel use.
The DSEP100 G99/G59 Mains(utility) Protection Relay detects changes in the mains (utility) supply to which the distributed energy resource (DER) is connected. If a mains (utility) failure is detected, the DSEP100 will disconnect the equipment in line with national and international DNO requirements. This removes the risk of an islanded grid being formed and protects DER

So "what actually happens during G59 commissioning" is a question I was asked earlier this week. It came up, as we had been doing exactly that, deep in the bowels of Kings Cross Station. 40th European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC 2023) 18 September 2023. CCL Lisbon Congress Centre, Lisbon, Portugal. More
The G59 relay protective device, in simple terms prevents this situation by automatically disconnecting the embedded CHP from the mains. 2. What does the G59 Device Actually Do? Note if the site has solar PV the facilities for this will need to be shown as well as the CHP / Generator. (The G59 relay Comap MainsPro will be mounted within the

ComAp provided a flexible, user-friendly and cost-effective hybrid controls package that alleviated problems we were facing with the integration of high penetration solar PV and battery storage into the Mayreau power system. The performance of their solution has far exceeded our expectations.
– DC Voltage: the first thing to define is the Vdc of the connected solar PV array or wind turbine output. This could be 12, 24, 48, 96Vdc or greater. Knowing the Vdc figure provides our engineers with the necessary information to specify the battery blocks required per battery string.
FULLY G99/1 & G98/1 COMPLIANTG99 Type Tested Variant - Now Available (DSEP100-02)The DSEP100 G99/G59 Mains(utility) Protection Relay detects changes in the mains (utility) supply to which the distributed energy resource (DER) is connected.If a mains (utility) failure is detected, the DSEP100 will disconnect the equipment in line with national and international DNO
Any generators installed before February 2018 with a G59 relay needs to be updated to the new G99 relay rules by September 2022. Those who act quickly may be able to have costs reimbursed through the Accelerated Loss-of-Mains Change Programme (ALoMCP). Benefits of solar PV ; How does wind energy work? Renewable Energy Solutions - Install
It seems the decision to install a G59/2 relay unit is really in the hands of the DNO, whether the inverters are G59/2 certified or not. Reply to Mac Jobio Reply to G59 relay panel in the Solar PV Forum | Solar Panels Forum area at ElectriciansForums
