FUNCTION
The Reverse Power Relays detects the
active power passing on an electric line
and are capable to point out the
direction of the power itself.
It is made of a logic, which is universal
and by a CT (current transformer). Up
to 5A the CT inside the device is used.
For current > 5A, an external CT is
required (see TAB.A)
The CT covers the active power
passing in the usual direction (from
generator to load). The relay does not
detect the power from generator to
load, but it detects the power from load
to generator.
USE
By detecting the direction of the active
power, it is possible to control when the
generator becomes a load and vice
versa
