Measuring
and displaying the load current, line voltage, electric
power, electric energy level, harmonic current ( third,
fifth and seventh ) and earth leakage current* enables
energy management
Measures and displays
the cause of the fault event and the event's load
current ( over load current or earth-leakage current
).
Event when the control power is cut, a record of
the event's cause and the load current are saved in
the MDU's memory.
Since the maximum value of the demand load current
and the time of occurence are measured, this is helpful
for locating the peak time for energy use.
The measuring VT and CT are installed in the circuit,
thus offering savings on space and wiring .
The measuring display unit can be installed on the
circuit breaker onto the panel. |
