One of the smallest, most cost effective instruments for the measurement and analysis of single and three-phase electric power.

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.

True RMS Current

Current measurements – A,B,C, and neutral current inputs for 1Ø and 3Ø circuits. Maximum, minimum, average, and present value for each phase to neutral current. True RMS values provide accurate measurements regardless of waveshape. The photo above shows phase A current (Ia) levels.Toggle content goes here, click edit button.

Power Factor

12 Power Factor measurements (W/ VA) accurate from zero to unity p.f. for all phases, maximum, minimum, average, present value,and total p.f. are available as standard. The photo above shows phase A to neutral power factor readings.

Transient Spike

12 Power Factor measurements (W/ VA) accurate from zero to unity p.f. for all phases, maximum, minimum, average, present value,and total p.f. are available as standard. The photo above shows phase A to neutral power factor readings.

True RMS Voltage

watt-3030-p2b_num2

12 True RMS voltage measurements for 1Ø and 3Ø applications including maximum, minimum, average, and present values. The 3030A true RMS voltage levels provide accurate measurements for distorted or non-sinusoidal wave forms.

Frequency Display

Frequency and Duty Cycle measurements are also available. Ideal for field or on-site use, the Valhalla 3030A can easily perform “power on” duty cycle ratios ( % ON/OFF) for motors, refrigerators, compressors. air-conditioners, and a variety of thermostatically or relay controlled devices.

Peak Demand Period

watt-3030-p2b_num8

As a power Data Logger the Valhalla 3030A records the peak demand period (i.e. period of day) when the most energy is used, along with the average power demand for each demand interval automatically. The Valhalla 3030A allows complete interval entry flexibility, from 1 second to a 99 minute demand period.

True RMS Power

watt-3030-p2b_num3

8 true power measurements as well as apparent power (VA). Both parameters (true power, and VA) are measurable as a maximum, minimum, average, and present values for any phase (A, B, C, and total power).

Total Harmonic Distortion

watt-3030-p2b_num4

12 Power Factor measurements (W/ VA) accurate from zero to unity p.f. for all phases, maximum, minimum, average, present value,and total p.f. are available as standard. The photo above shows phase A to neutral power factor readings.

Estimated Cost/Year

watt-3030-p2b_num9

Ideal for energy audits, the Valhalla 3030A measures actual energy use (KWHr & true cost), estimated energy use per hour, day, month, and year. It also accepts user adjustable utility rates.

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.

PC Control Analysis

PC control/analysis capability allows high resolution voltage and current wave forms to be uploaded to your PC.

Harmonic & PC Control

Harmonic and PC control analysis links the measured waveform for graphic display of harmonics from the 1st thru 50th to your PC.

Line Disturbance Analyzer

Fluctuations in power consumption or device under test power levels may be graphically displayed or imported into your presentation or spreadsheet software.
