3.8 Transformer
Please note! It is not permitted to use the outputs
of Janitza measurement devices and components
for switching protective devices or protective re-
lays! Use
only “Current transformers for measuring
purposes” for Janitza measurement devices and
Janitza components!
“Transformers”, unlike “protection transformers”,
go into saturation at high current peaks. “Pro-
tection transformers” do not have this saturation
behavior and can therefore significantly exceed
the rated values in the secondary circuit. This can
overload the current measurement inputs of the
measurement devices!
Furthermore, please note that Janitza measure-
ment devices and components are
not to be used
for critical switching, control or protection applica-
tions (protective relays)!
Observe the safety and warning information in the
chapters „7. Installation“ on page 28 and „2.3
Product safety“ on page 13!
3.9 Operating concept
