Designed for users with energy-saving needs, the EAS630 electric energy analyzer demonstrates a new way to help users quickly find the source of wasted energy. Various new features help users identify energy-saving aspects and provide energy-saving data support. The EAS630 is your best choice for performing energy surveys and energy-saving professional energy analyzers.
It can be seen from the electricity expenses of the enterprise that the basic electricity fee is 0.57 yuan / KWh, but due to the power factor electricity tariff adjustment (fine), the monthly electricity expenditure is 98.76 yuan. The unit price per average electricity bill reached 1.72 yuan.
What is the reason for the excessive electricity expenses of the company? Is there room for energy savings? What is the economic benefit of energy saving? The EAS630 three-phase electric energy analyzer is perfect for users to conduct energy consumption analysis and investigation!
1. Energy survey first step: power measurement
First, the overall power needs to be measured to clearly understand the power and energy consumption of each phase;
Figure 1, power decomposition diagram
Conclusion: It can be seen from the power measurement data that the apparent power and non-active power of the enterprise are large, which is the direct cause of the low power factor.
2. The second step of the energy survey: Looking for the root cause of waste Why do the apparent power and non-active power are too large? The “Power Decomposition†function under the “Power†measurement page of EAS630 provides the apparent power and non-active power decomposition functions to help you analyze the reasons further:

(Figure 3) Reactive power composition
Conclusion: From the page of apparent power decomposition, we can see that the unbalanced power and non-fundamental apparent power account for about 50% of the apparent power. This part of the power does not work for the used equipment, which is unbalanced at the load end. The introduction of non-linear load, this part of the power will increase the output capacity of the transformer, so that the overall power consumption efficiency is low. To reduce the basic electricity cost and increase the power factor, it is necessary to reduce the power of these two parts, adjust the load balance, and filter the filter unless the fundamental wave Part of the capacity to achieve energy savings.
In the non-active power page, we can see that the current distortion power, the fundamental positive-sequence reactive power account for the main component, the fundamental reactive power is caused by the phase difference between voltage and current, and the current harmonic distortion power is due to the harmonics in the current. Caused by more components, the two parts of the power itself do not use electricity to do work. The two powers are reduced by means of reactive power compensation and harmonic control, which can reduce the non-active power content and improve the power factor. And it can reduce the line loss, achieve energy-saving purposes, and reduce electricity bills.
Energy Survey Step 3: Quantify Loss Current Power
The unique current decomposition method adopted by EAS630 independently calculates the active, reactive, harmonic, unbalanced, and neutral currents. Since the power line circuit has a certain resistance R (IEC 317), the current will generate a certain amount of active power in the transmission line. Consumption, this part of the energy loss will cause the meter to increase billing, causing additional economic losses. The EAS630 quantifies this loss.

Summary: For high-energy production enterprises, electric energy is the main resource of enterprises, how to do energy management! First of all, to find out the waste of enterprise power consumption, we must do a good job in the measurement and analysis of power management, the reason why enterprises do not do energy-saving measures, there are several problems: 1. Can not grasp the current status of energy consumption, 2. Can not Quantify the energy efficiency indicators of the company. Collecting and analyzing scientific energy consumption data is the most powerful guarantee for enterprise energy conservation indicators. The EAS630 three-phase electric energy analyzer of Guangzhou Zhiyuan Electronics Co., Ltd. is your best choice!
