Equipment for power systems are network analyzer to measure the network settings. It is commonly used to study the flow of power, short circuit calculations and to study the stability of the system. Network analyzer is an instrument of work in general a high frequency because it is the best way to measure the reflection and transmission of electricity networks, and size parameters in high frequency s-parameters or parameters diffusion. But for different purposes and needs, there are also network settings of the parameter y, z-paramaters and h-parameters are fixed. Two-port electrical network is the most common devices that use a network analyzer to describe the network. Examples of two-port network and amplifier filters. Mainly used in high frequency operating range of the network analyzer 9kHz to 110 kHz. For the lower frequency range specific objectives can also be used by other types of network analysis to 1kHz. But in general there are two types of network analyzer, are not ranked in the frequency range, but the properties measured. Both types are scalar network analyzer (SNA) and the vector network analyzer (VNA). SNA measure only the properties of the amplitude of the electric grid while the two aplitude VNA measurement and also the power system phase. The most common use of instruments in the world is the VNA, which is why you are more likely to find vector network analyzers on the market rather than a scalar type.
As the network analyzer technology development, the network analyzer has created a new category. New category called transition analyzer microwave (MTA). The network analyzer can measure both the amplitude and phase of the same properties of the grid with the VNA, but improved in measures of both fundamental and harmonic. MTA is also called the large network signal analyzer (tons) which increases with the ease of calibration. As we know the calibration is very important in any test instrument. It is one thing that guarantees action is correct and accurate. Calibration must be done on a regular basis, there is also a privileged moment of calibration needs such as after an error or after the instrument is not used for a long time. Thanks to the easy calibration, the use will be easily calibrate to save time. There is also a network analyzer that uses automatic calibration to save more time and convenience. Each type of network analysis have different functions, different benefits and disadvanatges. For different reasons, you will need a different network analyzer. Price is also one of the main considerations, to high technology can bring a higher price. Learn the complete specifications before buying.
