MHO distance relays are used to protect andÊdetect faults and the location of faults on a transmission line. It detects faults by measuring and comparing phase angles through a phase comparator.
as it is most affected by arc resistance....
A mho is a unit of electrical conductance, representing the inverse of resistance. It is equal to one siemens, which is the standard unit of conductance in the International System of Units (SI). The term "mho" is derived from spelling "ohm" backwards, emphasizing its relationship to resistance. One mho indicates a conductor that allows one ampere of current to flow with a voltage of one volt across it.
A relay cannot be used to power a motor. It can be used to control the motor by wiring the motor circuit in series with the relay contacts.

mkjj
mho rerlay is used in long transmission lines
as it is most affected by arc resistance....
MHO is a formerly used unit which was used to measure electrical conductance.
The correct spelling is siemens, and it is the SI unit for conductance -the reciprocal of resistance. The mho is simply an obsolete unit for the same thing, and is numerically equal to the siemens.
First of all, the correct spelling is 'siemens' (symbol: S), which is the SI unit of measurement for conductance -the reciprocal of resistance. The mho is simply an obsolete unit for conductance, and is exactly equivalent to the siemens.
it measure the hardness of material.
no jade is like an emerald and agate is more like the ruby NO !!!!!!! MHO- scale is the same for both stone though some time in formation jade well be a 6.8 - 6.9 / as agate is a hard 7.0 MHO-scale. Emerald & ruby ...... 8.5 MHO - scale Sorry that this answer was ......Blank in wrong
Bhala ka sa buhay mho..bkit qoh nmn sa2bhin ed nlaman mho.,..tanga mulala berat baliw nga nga
