LIVE START-UP CIRCUIT FOR BANDGAP REFERENCE (BGR)

Patent no: 369348

The patent 369348 discloses a live start-up circuit for a Bandgap Reference (BGR) for providing an even distribution of a Monte Carlo analysis. The circuit includes a plurality of transistors and a resistor. A current across transistors is given as a gate voltage to the transistor. The voltage from the transistor is given to node B of the BGR for keeping a BGR operations ON through an ON period of BGR for the even distribution of the Monte Carlo analysis and for compensation of Temperature Coefficient (TC).

HIGH VOLTAGE (HV) SURGE TESTER

Patent no: 442767

The patent 442767 discloses a High Voltage (HV) surge tester (100) for diagnosing failure in underground power distribution cables. The invention achieve this by providing microprocessor to control the operations of surge tester. The microprocessor is configured to identify a variance in an energy of the HV transformer and enables a start of a surge testing of the underground power distribution cable. The variance gradually increases from zero to an output energy to obtain spark across a faulty cable.
