Wind power is a renewable energy source that is being aggressively promoted (particularly in Europe) in order to reduce emissions of the greenhouse gasses that are responsible for global warming. The advantages of wind power and other renewable energy sources are that it does not require fuel, and can generate power day and night.  There are two systems for generating power: the DC link and AC link systems. The WT500 Power analyzer enables analysis of data in each of these generation systems with high precision.

Measuring Fluctuation In Voltage

Example of Measurement with the WT500

DCLink System
  1. Waveform observation of the fluctuations in voltage frequency and value
  2. Observe the voltage value of the converted DC signal
  3. Observe the voltage level and stability of the converted AC signal (50 Hz or 60 Hz).
  4. Observe the stability, suddenly emerging phenomena, and other characteristics of the 50 Hz/60 Hz 100 V/200 V signal.
AC Link System
      5.  Observe the voltage level of the signal output at 50 Hz/60 Hz.
      6.  Confirm whether output at 100 V/200 V is stable.

Power Analyzers

Power Analyzers

A power analyzer measures electrical power characteristics of devices that generate, transform, or consume electricity. Also called power meters or wattmeters, these devices measure parameters such as true power (watts), power factor, harmonics and efficiency in inverters, motor drives, lighting, home appliances, office equipment, power supplies, industrial machinery and other devices. Power analyzers also enable engineers to minimize energy loss due to distorted, transient waveforms in power electronics such as inverters, motors, lighting circuits, and power supplies. 

Yokogawa, the world's leading manufacturer of electrical power analyzers, provides a broad selection to satisfy all requirements.
