M 219
M 219
The ARM® Filter M 219 is the coupling unit for connection of the Teleflex M or the Teleflex T 01/6 Time Domain Reflectometer and a Surge Generator for prelocation of high resistive and intermittent faults.
By means of the Surge Generator and the choke in the M 219 Filter at the fault point a flash-over is created. This flash-over converts the high resistive fault temporarily in a low resistive fault. Now the fault causes a reflection that can easily stored in the Teleflex.
The comparison of the traces before the flash-over and during the flash-over clearly shows the fault distance. The connection circuit is shown on the cover of the ARM® Filter M 219.
