PRODUCTION OF ENERGY AT THE LOCATION
If on location there is also production of electrical energy present
(photovoltaic cells, batteries, ...), the measuring current transformers can
be set on two conductors (production conductor and consumption
conductor). In this case the Load Guard would be measuring the
difference of consumption and production currents and would enable
higher charging current in time of production.
