Importance of Tools like Cable Fault Locators and ECG Machines

Man is surrounded by machines to the limit that for everything we do, we need the help of machines. Anything that reduces human labor, from an airplane to a hairpin, is a machine. The engineers and the doctors also need machines to help and to treat. Be it thermometers, inch tapes, stethoscopes or screwdrivers, these things have become so important in our lives that we would be at a loss without these things. Imagine a day when there is no electricity at home and you come to know that there is a cable fault; your first reaction will be to look for a cable fault locator and get the fault fixed. You might not even know what a cable fault actually is, but your dependency on machines tells you that there must be a device that will be able to find a way out of this situation.

A cable consists of multiple wires or electric conductors that are held together with a covering. It is used to transmit electric power and they are usually buried underground. Each cable has a limit of power supply. When this limit exceeds, or one of the wires becomes weak, there is a short circuit causing a spark and then a minor or major explosion. This explosion causes the cable to explode leaving all the buildings that were supplied with electricity from here in darkness. To fix this issue, a cable fault detector is required. Since the cables are under ground, the detector first identifies the location where the explosion has taken place. Once that portion has been identified it is dug out and the cable there is fixed either by providing new wiring, or increasing the wire strength. Usually there is a cable fault locator underground. The cable fault finder receives signals from this locator and the arrow on the finder points to the position where the digging and maintenance need to be done. Fixing a cable fault is tedious and laborious. But without a cable fault locator, this task is impossible.

Our dependency on an ECG machine is quite similar to the cable fault locator. Without this machine it would be impossible to know the electrical activities of the heart. The human body produces an electrical current through the heart. At times, this current grows or diminishes in intensity indicating that the heart is not in proper shape. The ECG machine helps us to understand the exact problem that is causing the heart to malfunction. The machine can have either 12 leads, or 5 leads or 2 leads to study the rhythm of the heart. These leads are connected to the arms, the legs and the chest to get the readings that appear printed on a strip of paper that ejects out of the machine. The positioning of the leads as should be on the body is elaborated on the manual that comes with the ECG machine. These readings indicate the health of the heart and tell you whether or not you should be under medication. Such electrical and medical machines help in various activities of our lives.
