Evaluation of lighting devices

Testing of high frequency lighting devices often involves measurement of voltage, current, and Total Harmonic Distortion (THD), a parameter that indicates the quality of power. This is because distortion in voltage and current waveforms is becoming more prevalent due to the increasing complexity of control systems.
The WT3000E can simultaneously measure voltage and current with THD, and allows for more accurate and rapid measurements of an instrument’s characteristics and fluctuations.
Currently LEDs are rapidly replacing incandescent light bulbs and compact fluorescents (CFLs). The main reason is because LED lighting is more energy efficient. In case of LED lighting systems it is important to measure small DC currents and the dimmer control circuit needs high frequency measurement capability.
Both 2 A and 30 A input elements can be installed in the same WT3000E and provides up to 1 MHz broadband performance.
Thus users are able to fully evaluate their LED systems.

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.
