Network analyzers for effective power supply control
Network analyzers are multifunctional devices used for detailed monitoring and evaluation of power network parameters. The devices help detect deviations, increase energy efficiency, and ensure reliable operation of equipment. They are in demand in both industry and the household sector.
What parameters can a power grid analyzer measure?
The analyzer records the main indicators. It shows:
- voltage level;
- current strength, frequency, power;
- the amount of energy consumed;
- quality of power supply.
Network analyzers measure voltage in single-phase and three-phase systems. This way, the stability of the power supply is assessed, and voltage surges and drops are detected. Accurate voltage and current measurements are essential for diagnosing faults and preventing overheating of wiring.
The network analyzer helps to measure harmonics - high-frequency components of alternating current. Their excessive amount leads to overheating of transformers and cables, disruption of sensitive equipment. And the power factor shows the efficiency of the electricity used.
Modern network analyzers record even minimal fluctuations in the frequency of the electric current. This allows you to quickly respond to problems in power systems.
In three-phase networks, it is important to maintain a balance between the phases. Network analyzers determine the level of phase asymmetry and help to adjust the load distribution to normalize the system.
How to choose a network analyzer
The choice of a power grid analyzer depends on the monitoring tasks, type of equipment, and measurement accuracy requirements. The main criteria that will help you choose the best device are:
- measurement range;
- availability of data recording and storage functionality;
- compliance with international standards.
The measurement range is one of the main parameters that determines the ability of the device to record readings in the required conditions. For domestic and commercial networks (single-phase 220 V), devices with a range of up to 300 V and up to 100 A are suitable. For industrial networks (three-phase 380/400 V), analyzers with the ability to measure up to 1000 V and higher, and control current up to 5000 A are chosen.
For power consumption analysis, fault diagnostics, and long-term monitoring, network analyzers have an important data logging function: loggers with long-term memory or devices with short-term recording. Recording parameters helps to identify hidden problems, assess the efficiency of the power system, and prevent malfunctions.
The device must meet quality and safety requirements, especially if it is used in industry or certified power systems. Compliance with standards guarantees measurement accuracy, interference protection, and equipment durability.
How do I install and configure the network analyzer?
To connect the device, select the network node with the highest value for monitoring (input switchgear, main switchboard). Install current transformers (CTs) and voltage sensors taking into account the rated parameters of the network and current direction. Configure the fixation frequency and measurement range, as well as the data transfer protocol in the analyzer interface. Perform test measurements and adjust the parameters if necessary.
How to read data from the device correctly
Correctly use the factory interface or SCADA system by selecting the desired protocol (Modbus, IEC 61850). Check the correctness of the data from the network analyzer using vector diagrams and event logs.
Can I use a network analyzer to detect power supply problems at home?
Yes, there are certain models of devices that are suitable for use in the home. They help to detect loads in power grids, voltage instability, and other problems.
How often to calibrate the power network analyzer
The network analyzer needs to be calibrated every 1 to 3 years, depending on the manufacturer's requirements, accuracy class, and operating conditions. Regular verification with reference instruments allows you to detect drift in readings and prevent measurement errors. In critical systems with high accuracy requirements, it is advisable to perform verification annually.
