Deep Sea Electronics - Mains Decoupling Relay FULLY G99/1 & G98/1 COMPLIANT 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 equipment. DSEP100 is suitable for use with all DER equipment supplying power in parallel with the mains (utility) supply. This includes diesel generators and renewable energies such as photovoltaic (solar) and wind turbine installations etc. CONNECTING TO THE MAINS (UTILITY) From 27th April 2019 new Grid Codes replaced G59 in GB. From that date all new distributed energy resources (DERs), formally falling under G59 must comply with new regulation G99. The DSEP100 Mains Decoupling Relay is compatible with G99. NB. Existing DERs in GB (connected prior to 27th April 2019) need to be aware that G59 has also been amended. This means that connected equipment, which complied to G59 on installation, may no longer comply. If you have an existing DSEP100 no new equipment is necessary. Simply change the settings through DSE Configuration Suite PC software. To view UL Certification click here.
