AL404 Series portable digital fault recorder and analysis system

Implementation of standards.

DL/T 684-1999DL/T849.1-2004IEC60255-24:2001

 

Series portable digital fault recorder and analysis system which has been widely applied to power system can record the transient and steady analogue & event signals of generators and transformers, power transfer lines, station and plant, monitor the power system operation, store the test data, and also record and catch the fault information. So It, as an important instrument, provides keys to study the operation mode of power grid and estimates the characteristic of protection devices.

It was widely used in the area of power line, generators and transformers for monitoring, analyzing and recording while power devices is operating, testing or in maintenance.

Meanwhile, It has also been used for the oil or chemistry industry fields with monitoring and recording the signals coming from various kind of sensors such as flow quantity, temperature, liquid level, pressure and so on.

It series portable digital fault recorder and analysis system chooses the advanced technology in the world such as embedded micro-processor, international popular multitask real time LINUX operating system, DSP and networks communication technology. It is a new portable and all functions dynamic intelligent recorder and analysis instrument with full self-determination knowledge property according to the latest technology discovered in the area of generational power system. It has not only various excellent skills in full functions, reliability, stability, precision and portability, but also the special design of general channel for AC/DC voltage and current which introduces a patent of Wuhan-Fount, auto-discriminating of adapter, to distinguish automatically the types and range of all the adapter. As a result, it satisfied the users that various types and ranges of signal input channel would be wildly required.

Portable digital fault recorder and analysis instrument inherited all the functions and skills of It series digital fault recorder and analysis system.
