Meter inaccuracies
Losses due to meter inaccuracies are n nothing but a difference between actual energy supplied to the consumer through the meters and amount registered by meters. When meters it gives negligible errors in the metering, it gives
What is power theft?
Power theft is a problem which has been plaguing a power utility a problem which has been plaguing a power utility since it’s service and accounts for a significant amount of high transmission and distribution losses in
What is copper losses
Occur same as in distribution line and are lesser in quantity as compared to core losses. Copper losses are nothing but dissipated heat by the current in primary as well as secondary winding which can be found
What are copper losses by conductor
Copper losses can be minimized by the use of greater diameter of the conductor wire and winding material with better resistivity. Casually choosing the thickness, increases eddy currents. In this regard, sectionalisation is preferred in order to
Metal halide lamps
Light in metal halide lamps is generated by an electric arc through a gaseous combination of mercury vapours and mixtures of metal components metal halides. These additional metal halides in discharge tube emit their own spectra. This
Difference between feeder and distributer
Feeder Distributor In the substance (s), the voltage magnitude is reduced to a utilization level and then the eclectic power is a distribution to the various area through the conductors which is known as feeders. The distributor
Classification of oscillators
Classification of oscillators: Based on the output waveform: The oscillators are classified as: Sinusoidal oscillator Non-sinusoidal oscillator Based ON the circuit components: RC oscillators LC oscillators Crystal oscillates Based on the range of operating frequency: Low-frequency oscillators
Explain barkhausens criteria for oscillation
Barakhausens criterion: Consider a basic inverting amplifier with an open loop gain ‘A’. As basic amplifier is inverting it produces a phase shift of 1800 between input and output The amplifier to work as an oscillator two
Applications of nano-materials
The nano-materials find applications in various fields of- Medicine Nanomedicine and diagnostics- Nanogold particles selectively accumulate in tumours, providing precise imaging and targeted laser destruction of a tumour harming healthy cells. Bio-barcode assay is a comparatively cheap
Construction of gas pressure cable
Constructionally, pressure cable is similar to that of an ordinary solid type’s cable except that it has a triangular shape. Triangular formation helps to reduce the weight of the cable also the thickness of the lead sheath
