What are some potential problems you might face when grounding equipment?
What will be an ideal response?
Ground is generally thought of as being electrically neutral or zero at all points. However, this may not always be the case in practical application. It is not uncommon to find that different pieces of equipment have ground levels that are several volts apart. To overcome this problem, large cable is sometimes used to tie the two pieces of equipment together. This forces them to exist at the same potential. This method is sometimes referred to as the brute-force method. Where the brute-force method is not practical, the shield of the signal cable is grounded at only one end. The preferred method is generally to ground the shield at the sensor.
