UTP : Unearthed Universal Transient Protector - a small circuit connected to the input of any electronic equipment, acts as a total protector against short circuit, over load or transient impulses of any nature that would be a variant in the input supply line. UTP is interfaced between the input supply line and the load (equipment) and the input of the equipment is the output of the UTP. The UTP does not have, nor require an earth/ground terminal, thus making its applicability universal. The uniqueness of UTP is that it gives total protection against spike, short circuit, overload and transient impulses for the equipment which is operated with it, and the UTP does not create any major power or voltage loss to the input supply of the equipment.

The protection is given in the form of a fuse which would trip of at the occurrence of a transient impulse of any voltage of both polarities, with the phase angle of the superimposed transient impulse varied from that of the normal supply current wave; over and above protecting the equipment against short circuit or overload. Thus total protection is given to the equipment operated in the supply line and, UTP can be used either independently or can be integrated in the equipment as desired. The manufacturing cost of the circuit is less than 2 (two) US Dollars and the cost would further come down as per the scale of economy of manufacturing. UTP neither creates any additional harmonics (current or voltage harmonics) in the supply line nor generates any noise pollution during its operation. The technology of the UTP can easily be adapted to suit any wattage of load as defined by the equipment operated with it. All components used are purely electronic components and it is adaptable for functioning with input supply of 60 Hz, 110 V AC and 50 Hz 230 V AC.
