DSEP100

FULLY G99/1 & G98/1 COMPLIANTThe 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 are replacing G59 in GB.
From that date forward all new distributed energy resources (DERs),  formally falling under G59, will have to comply with new regulation G99.The DSEP100
Mains Decoupling Relay is compatible with G99.

NB. Existing DERs in GB (connected prior to 27th
April) 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 are using a DSEP100 its good news – no new equipment is necessary.  Simple changes to the settings through DSE Configuration Suite PC software is all that is needed.
