Yokogawa High Speed Measurement Option for Precision Power Analyzer

A new high-speed data-capture option has been introduced for the Yokogawa WT1800 precision power analyzer.

The new /HS option provides fast, accurate measurements of power parameters such as voltage, current, power, torque, speed and mechanical power with millisecond response. This allows it to capture numeric data on the change of status during one rotation of a motor when the motor is started, when the rotation speed changes, or when the load condition varies.

This new function takes advantage of the WT1800's sampling frequency (up to 2 MS/s) and its unique ability to carry out calculations on measured parameters in real-time.

The new high-speed data-capturing function can measure 3-phase voltage/current/power and torque/rotation speed/mechanical power every 5 ms (when external synchronization is off) or every 1-100 ms (depending on the clock signal frequency) if external synchronization is on. Wiring configurations include single phase for DC input, 3-phase 4-wire and 3-phase 3-wire (3V/3A).

It transmits a block of data every second to an internal or external memory or to a PC using a communications interface. Every second, the WT1800 updates its displays with the previous one second of data.

Major target markets for the WT1800 with the high-speed option include motor and inverter evaluation in the automotive and aerospace sectors as well as alternative energy and power conditioning applications.
