M-System would like to introduce its new lightning surge arrestor series, the M-Rester MD7 series. It will absorb only the lightning surges with no interruption of the instrumentation signal and offers superior protection and selection across a variety of applications.
Customer: Waterworks Plant
A municipal waterworks plant had quite a few issues because of lightning strikes in the vicinity. In their facility, there are many loops of water level control. They used numerous process instruments such as level meters, and wiring that was exposed to the outside environment. Whenever lightning struck around the area many instruments were destroyed due to the surge caused by lightning.
As the information was received, we visited the municipality and introduced our M-Rester series lightning surge arrestor. At first, they were dubious about the effects of the surge protector. As you know, it is very difficult to convince a government to use new products. However, after several visits, they installed our M-Rester on only a few of their many many loops. The next time there was a lightning storm in the area, they were very surprised to find that the instruments protected by M-Rester were not destroyed while many other instruments on the loops which M-Rester were not installed were destroyed. This made them decide to install the M-Rester on all loops.
M-Rester lightning surge arrestors should be used to protect a variety of field sensors, communications and power supply applications in all types of industry around the world. Further information may be found on the following M-System webpage ---> http://www.m-
