IMPROVING ACCURACY OF POWER AND POWER QUALITY MEASUREMENTS

Dave Coombes

Abstract

To calibrate power and power quality measurement instruments such as flicker meters or harmonic measurement devices, several alternative techniques are generally used or proposed:<br />
• Using a reference device to make measurements which can be compared against those made by the UUT.<br />
• Applying variable loads to a static, impedance loaded power line to induce required conditions.<br />
• Generating the required signals with a precision signal source.<br />
This paper discusses the third option. There are a number of benefits to this approach, as well as a number of difficulties
to overcome and decisions to be made to implement it effectively.
