The SMART NAVIGATOR is powered by an internal battery. For the function of current measuring the
unit is also energy harvesting from the overhead line.
The field replaceable battery provides operational power. Not only dependent on line current or
voltage for its power, the fault indicator is constantly “armed & ready” to register switching into faults at
any time.
The SMART NAVIGATOR is designed for an operational time of 15 years. If it detects that its battery
is approaching the end of its service life, the SMART NAVIGATOR will activate the low battery event.
