PC Software
Special SW Tools
Special tools enable a detailed, time domain based signal analysis. They represent a
powerful, modern troubleshooting tool for solving of all kinds of problems which are
appearing in power distribution systems. The user can choose between three modes,
differing in terms of sampling speed, trigger possibilities and recording time:
WAVEFORMS
Recording of voltages and currents with 128 samples/period.
Half period RMS values of recorded quantities are also
calculated and shown in this mode. Best suited for:
– monitoring of switching phenomena,
– locating of noise and disturbance sources,
– defining disturbance type,
– locating excessive harmonics sources.
Typical problems that can be solved by WAVEFORM analysis:
– capacitor banks switch over,
– transformer overheating,
– UPS problems,
– SMPS failures etc.
FAST LOGGING OF SIGNALS
Recording of half period RMS voltage and currents values.
Recommended when record length is critical and signal’s
details are not of importance. Best suited for:
– observing start up and inrush events,
– locating impedance problems,
– long term analysing of unstable mains.
Typical problems that can be solved with FAST LOGGING
analysis:
– too high inrush currents of large motors,
– undersized fuses and installation wiring,
– too weak voltage source etc.
TRANSIENTS
The recording mode with fastest sampling rate that the
instrument can provide. Up to 50 kHz transient detect ability in
this mode. Best suited for:
– monitoring atmospheric discharging,
– analysing switching problems,
– detailed analysis of high frequency noise and
notching.
Typical problems that can be solved with TRANSIENT analysis:
– frequency noise,
– voltage spikes caused by switching of capacitor
banks etc.
