A low noise constant current source used for measuring the 1∕f noise in disordered systems in ohmic as well as nonohmic regime is described. The source can supply low noise constant current starting from as low as 1 μA to a few tens of milliampere with a high voltage compliance limit of around 20 V. The constant current source has several stages, which can(More)
Boiler Tube failure is the prime reason of the forced outages at Fossil power plants. The generation loss due to the non-availability of the units, the compulsions to complete the inspection in the shortest possible time and the lengths of the tubes for inspection necessitate the use of robotic inspection systems in Boiler. Currently, there are no robotic(More)
