Harmonic Energy Analyzer
As a Harmonic
Energy Analyzer, the 3030A tracks percent of total
harmonic distortion (%THD). The % THD indicates the
degree of non-sinusodial waveshape the voltage or current
exhibits. Individual harmonic values (1st-50th) are
optionally available.
Line Disturbance Analyzer
As a Line
Disturbance Analyzer, the 3030A tracks voltage or current
disturbances (transients -up to 999 events). Amplitude,
duration and risetime are continously monitored; largest
transient data is logged. Swells and sags may also be
detected and logged.
Power - Energy Data Logger
As a Demand
Analyzer, the 3030A tracks power consumption, Energy,
Cost, Harmonic Distortion, True Watts, Kilowatt-Hours
(KWHr),True RMS Volts, Amps, True Power Factor (W/VA) and
more. Graphs and individual waveforms can be uploaded to
a PC for analysis.

Single and Three
Phase Harmonic Energy Analyzer - Data Logger
- The Valhalla
3030A is one of the smallest, most cost effective
instruments for the measurement and analysis of single
and three phase electric power. It lets the user
analyze energy usage and costs. You can evaluate power
quality, troubleshoot wiring and equipment energy use,
and perform true three phase measurements for less than
the cost of a single phase instrument.
- The Valhalla
3030A capability includes: single and three phase
voltage, current, power (watts), energy (KWHrs), cost,
power factor (p.f.), total harmonic distortion,
transients (spikes), frequency, duty cycle, and power
cycles. It also stores in non-volatile memory two
complete sets of waveforms (saves 14 signals-
3Ø) as standard.
- The Valhalla
3030A also measures 3Ø delta voltages - (i.e.
phase to phase voltages) and current levels as
standard. Primary/secondary ratios for current
transformers (CT¹s) and potential transformers
(PT¹s) can be entered into the unit for recording
of primary values when monitoring secondary outputs, to
provide automatic scaling for energy measurements (i.e.
Kilowatt Hours).
- The Valhalla
3030A measures each phase to phase voltage and current
in a three phase delta configuration. Total 3Ø
power factor may also be displayed. The PC Control
Analysis software provides simultaneous voltage and
current measurement sequencing. There is no waiting or
cycle time delays between the voltage or current
data.
