Power Quality Meter Definition

Normal utility power in the united states is supplied at a frequency of 60 cycles per second or 60 hertz 60hz.

Power quality meter definition. Power quality monitoring pqm has many benefits such as improving performance and quality. A pqm system will gather analyze and interpret raw electricity measurement data into useful information. Frequency close to the rated value and smooth voltage curve waveform resembles a sine wave. Power quality meter is a low frequency spectrum analyzer.

Three phase power quality analyzers are ideal for troubleshooting logging and creating detailed reports in conjunction with the easy to use energy analyze plus or powerlog 430 ii software. A typical monitoring system measures voltage and electrical current but ground quality may also be measured if unbalanced loads or harmonics are. Energy is the lifeline of your business and better efficiency and sustainability can have a large positive impact on your bottom line. Electric power quality or simply power quality involves voltage frequency and waveform good power quality can be defined as a steady supply voltage that stays within the prescribed range steady a c.

Find the right power quality tool. Find and solve power quality problems. On large interconnected utility systems such as srp s frequency is very stable and deviations are rarely a problem. For american power systems the 1 represents 60 hz the 1st harmonic or fundamental the 3 for 180 hz the 3rd harmonic the 5 for 300 hz the 5th harmonic and so on.

Programmable setpoints and 4 assignable output relays allow control functions to be added for specific. It provides metering for current voltage real and reactive power energy use cost of power power factor and frequency. The pqm ii is an ideal choice when continuous monitoring of a three phase system is required. Each number on the horizontal scale of this meter represents a harmonic of the fundamental frequency.

Three phase power quality analyzers are ideal for power quality testing troubleshooting logging and creating detailed reports in conjunction with the easy to use powerlog 430 software. Siemens recognizes that high performance facilities make for high performance business.
