Digital Three Phase Electrical Safety Comprehensive Three phase power quality analyzer energy analyzer

Product Description

Power quality refers to the quality of the AC power supply via the utility grid to the user, which normally means the good or bad situation of the electric energy in transmission line. Power quality problems are mainly caused by the load side of the terminal. For example, impact reactive load will lead to serious fluctuates to power network voltage, and decrease the quality of power supply.
With the development of power electronics technology, on one hand, it brought positive side to the modern industrial energy efficiency and energy conversion. On the other hand, while the power electronic devices are widely used in all walks of life, it also has brought new and more serious damage to the power quality, and has become the main source of harmonic in grid.
The increasing use of rectifiers, frequency control devices, electric arc furnaces, electric railway and a variety of power
electronic devices in each distribution system, impact the electricity network or called power pollution. It causes voltage
instability, over-voltage, generates harmonics and so on. Harmonic makes efficiency of electricity production, transmission and utilization reduce, so that the electrical equipment will be overheat, vibration and making noise, and insulation aging, shortened life expectancy, and even failure or burned. Harmonics can also cause localized power system an occurrence or series resonant parallel resonance, so that the harmonic content is amplified, resulting in capacitors and other equipment destroyed.
Electrical properties of non-linear, impact resistance and unbalanced of these kind of load, causes serious pollution to the
quality of power supply. Thus, eliminating the higher harmonic problem in supply and distribution system has a very positive meaning in improving the power quality issues and ensuring power system security, stability and economic operation.
On the other hand, electrical equipment in modern industrial, commercial and residential users are more sensitive to power quality, and have a higher requirement of quality of power supply. Currently, harmonics, electromagnetic interference, power factor reduction have been tied to the three hazard of the power system.
When it is interfered or contaminated, grid power quality can’t reach the national standards, so it has to be targeted on the grid power quality improvement. To understand the actual situation of power quality, you must have the appropriate equipment to test and analysis the actual situation. Counter the domestic condition, our company developed the professional power quality analysis instrument, which is suitable for the country. The following will illustrate the specific performances, parameters, methods of use on the power quality analyzer in detail.
