What is the basic function of a megger?

A Megger is a device that will test the insulation of the circuit it is connected to. It produces a DC voltage to check for leakage current from the conductor to ground. It then will give you the value of insulation in Mega Ohms. Generally anything less than one Mega Ohm per thousand volts is poor insulation. Be careful when using this device because it does produce high DC voltages and it can give you an awakening jolt. It is most...

How do you test tensile strength of rope?

The same way that you test the tensile strength of anything - break it in a universal testing machine! You have to be careful how you hold the rope though - you obviously cannot grip it the way you would grip a metal specimen (since the grips will cut the rope). Therefore the rope may be locked into special rope-testing grips or tied around a T-bar or pin in a particuar way. As long as the rope breaks n the central "guage...
