Advantages for the Customer
Customers have the following advantages:
•
simple connection, easy installation,
•
high degree of safety through monitoring voltage, frequency and im-
pedance jumps,
•
high degree of reliability through automatic, continuous calibration of
the impedance measurement,
•
continuous automatic self-test of the isolation unit,
•
replaces the isolation unit provided by the public electricity supplier
which must be permanently accessible,
•
avoids inadvertent triggering through automatic adaptation of switch-
ing thresholds to the mains supply conditions,
•
minimum energy consumption, minimum heating up,
•
automatic, maintenance-free operation without recurrent tests,
•
automatic synchronisation and limitation of signal strength following
frequent use (several ENSs in local mains power supply).
