What is the difference between a power quality tester and a power quality analyzer?

The power quality analyzer is an industry measurement tool that records and analyzes power quality problems in the power grid, which can capture common power quality problems such as harmonics, voltage fluctuations, flicker, power and three-phase imbalance at the fault site, and provide performance evaluation and governance decisions on power quality for smart grids, new energy, electrified railways and large industrial users. Generally speaking, the power quality analyzer can include the power quality monitoring device, but the general power quality analyzer on the market refers to the portable power quality equipment, which is small in size and can be measured with the go, and the power quality monitoring equipment is installed and operated at the test site for a long time, and the data is transmitted in real time, so it is called "** type".

Similar. 1. It can measure voltage, current, power, harmonics, and flicker (some power analyzers can) 2Simple waveform review and analysis, and save data.

3.The voltage is generally within 1000V, and the current can be measured according to the current sensor.

Difference. 1.The bandwidth of the power analyzer is generally 10m, which is suitable for measuring the frequency conversion signal in the range of 0-10m, and the power quality analyzer is generally 45-65hz, which is suitable for measuring the signal of the power grid and the power frequency equipment connected to the power grid.

2.Sampling power analyzers can reach several meters, and the best power quality analyzers are generally within 1m.

3.The power quality analyzer is a device that uses the power quality standard as the limit value, triggers the limit value of the machine, and records the power quality event. There is no standard for power analyzers, as long as they can be tested within the bandwidth.

Fluke now has authorized distributors in more than 100 countries around the world and employs approximately 2,400 people. Over the years, Fluke Electronic Instrumentation has created and developed a specific technology market – providing high-quality electronic instrumentation products for testing and detecting faults in a variety of industrial sectors, and elevating that market to a significant position.

Yokogawa Yokogawa Group was founded in 1915 and is headquartered in Tokyo, Japan. It has 92 subsidiaries in 59 countries and regions around the world. The business field involves measurement, control and information, and it is one of the most professional multinational companies in the world in the industrial control industry.

In 1975, it took the lead in developing the world's first epoch-making distributed control system (DCS system), which measured, monitored and controlled the production process of large-scale factories such as petroleum and chemical industries, and made great contributions to the development of industry and social progress. Founded in 1889, Megger is a company specializing in the manufacture of power test equipment and power system measuring instruments. Megger is currently the world's largest manufacturer of electrical test and measurement, with 5 manufacturing facilities in the UK, USA, Sweden, Germany and sales in more than 170 countries**.

Domestic high-end power quality analyzers include Rioki (Shanghai) ******, Wuhan Huarui Yuanda Power Equipment, etc.

**The signal input terminal of the power quality testing device should be fixed, connected and pressed with screws. Usually, the current is connected in series with the loop. Of course, if the number of current channels is small, the current clamp can also be used for input.

The premise is: the current clamp is small in size, and there is a clamp position on the wire loop and can be fixed.
