LZZBJ9-24 Electrical Waterproof High Accuracy Current Transformer for Substation Usage

 
Transformer, also known as instrument transformer, is a collective term for current transformer and voltage transformer. It is a primary equipment that realizes the interconnection of electrical primary and secondary systems. Transformers convert high voltage and high current in the primary system into low voltage and low current for use in measuring instruments, relay protection, and automatic devices in the secondary system. It is not only a connecting element between the primary and secondary systems in the power system, but also an isolation element.

1. This current transformers are Accurate measurement for protection, wide range, and complete model specificationsAccurate measurement of protection can provide excellent safety factors and enable such sensors to operate in high-pressure environments. The range covers the vast majority of common industries, and the total number of product specifications provided far exceeds that of competitors, making it more suitable for customers to choose from..


2. This current transformers are Wide frequency band, can accurately measure from DC to several hundred kHz, wide screen band enables sensors to accurately measure almost all types of data signals, including DC, communication, surge current, etc., and can accurately reproduce the waveform of the measured data signal.


3. current transformers areSmall in size and light in weight, current transformers use digital power amplifiers for operation. In the mid to low frequency range, digital power amplifier power supply circuits are used to compensate, which can prevent the application of large and heavy voltage transformers.


4. This LZZBJ9 series current transformers are Good temperature and time characteristics.Current transformers have excellent temperature characteristics and can operate in open temperature ranges, with accuracy almost unaffected by temperature changes. They can maintain high precision characteristics throughout the entire temperature range. This feature does not change with the passage of time and can maintain excellent accuracy throughout its entire lifespan.


5. This type LZZBJ9 model Current transformers can provide a high level of accuracy, which is two orders of magnitude higher than traditional planning schemes. The additional benefit of high precision is that it can still ensure high accuracy even in a very small range (1% or less) within a wide dynamic range. This prevents the detection system from switching ranges under high sampling rates for precise measurement, significantly reducing system software costs and improving service life and reliability.
