On the front panel, the display soft-keys and rotary control are used to select the measurement to display from each channel or group of channels. Voltages up to 2000 Vpk may be connected directly to the measurements channels and a wide variety of current transducers may be used including wide bandwidth, resistive current shunts from Voltech. Accuracy is 0.02% reading + 0.05% range for (basic voltage and current) The PM6000 samples at a minimum of 5 MSPS (mega samples per second) and a maximum of 40 MSPS ensuring alias free measurements at up to 10MHz.

Voltech PM3000ACE three-phase analyser

The Voltech PM3000 ACE three-phase analyser is suitable for the measurement of all phase and line current and voltage parameters, total and displacement power factor, power and energy, comprehensive harmonics for voltage and current as well as short- and long-term flicker in compliance with IEC requirements. The Voltech PM3000 ACE locks on to the motor drive frequency of variable speed drives, making measurements over the full 1 MHz bandwidth and can compute drive efficiency through the input of torque/speed parameters and the instrument’s ability to apply scaling factors. The scaling factors of the Voltech PM3000 ACE also make it suitable for power transformer testing and the determination of K factors in transformers used to supply high harmonic content loads. The Voltech PM3000 ACE through its software displays waveform, data logs, harmonic bar charts, cycle-by-cycle rms data, etc. The Voltech PM3000 ACE utilises six monotonic A/Ds, three for voltage and three for current, the latter being equipped with high accuracy single shunts thus providing highly accurate frequency and phase performance. Digital signal isolation prevents errors typical of many analogue designs.

Voltech PM1000+ single-phase analyser

The new Voltech PM1000+ Precision Power and Energy Analyser is suitable for standby power, energy and inrush current measurement. Voltage and current can be measured to 600V rms and 20 Amp rms with crest factors to 20, respectively. Power, apparent power and reactive power can be measured to 90 kW/VA as well as power factor from –1.000 through 0 to +1.000, in the frequency range from DC and from 10 Hz to 1 MHz. Energy can be measured in watt-hours and VA-hours utilising integration windows from 1 to 300 seconds. Harmonics are analysed to the 50th order for both current and voltage, as are THD for voltage and current. A Voltech Ballast Current Transformer is available to permit accurate energy usage data for fluorescent lighting having current and voltage phase errors of less than 1º and 3º respectively. For power line analysis the instrument can be equipped with clamp-on current and voltage transducers. The Voltech PM1000+ is provided with Windows compatible software, USB, IEEE and RS232 ports and is thus suitable for use in production or R&D environments.

ATi Transformer tester
Automatic high speed transformer testing includes an LCR meter, and will test ferrite type transformers and components at frequencies selectable from 20Hz-3MHz. The instrument can be configured with over 30 measurement parameters including LCR, Z, M, turns ratio, etc. It is suited for high-speed production testing or manual impedance measurements. Testing of multiple windings is possible within a test routine, not only primary to secondary but also secondary-to-secondary windings. Typically ferrite transformers tested in less than 2 seconds. .
