Smart meters appeared on the consumer scene with the Reinvestment Act
back in 2009. However, for plant and factory management, energy
efficiency challenges have been around for some time. Software is a big player for managing energy at a plant level, but there are smaller investments that can go a long way, such as power meters.
The clamp-on power meter from Yokogawa combines the basic functionality
of a standard clamp on tester, digital multimeter and a power monitor to
initially diagnose maintenance and electrical issues. The early testing
is done with this portable instrument and more sophisticated
equipment can then analyze the performance of motors, generators and other
power related equipment.
This product offers technicians and maintenance personnel the ability to
measure 600 A AC/DC, 1000 V AC/DC, 600 kW AC/DC, power factor, total
harmonic distortion, harmonics from 1st to 25h, resistance and
frequency. Other capabilities include phase rotation, voltage detection,
continuity check, diode test, inrush current and low pass filter.
Comes equipped with a joystick to allow the user to easily select the
preferred diagnostic function. This portable instrument's display is
backlit when clamping and contains a 3.5. digit and bar graph display.
Meets CAT IV 600 V and CAT III 1000V safety standard and is CE rated.
