What are core lamination
Laminations mitigate the eddy currents. The iron core is formed by laminations dipped in insulating varnish. Sliced core offers very less width to circulated eddy currents. Silicon steel sheets to replace with solid core break up the
Isolating transformer
Usually, the electrical transformer is used to either step up or step down the voltage. It hardly does anything to minimize the crossing of noise or transients from primer to secondary. Circuit impedances can be by using
What is belt drives
One-third populations of motors in industrial and commercial sectors include belt drive as it avoids transmission loss. Increase decrease in the speed of the drives equipment is achieved with pulleys of various diameters. A well-designed belt transmission
What is changing to a different winding
In the rewinding with the option, lap winding is often preferred to be used as it includes all the same coils. This is quite acceptable if it results in the same amounts of flux per pole as
What is copy rewinding
If as noted earlier when details of manufacturer’s original winding are preserved the core can be made ready for rewinding. The points which will remain same as those of original windings are: Coils pitch Turns/ coils Connections
Types of re-lamping
There are two types of re-lamping: Groups re-lamping Sport re-lamping Group re-lamping Group re-lamping is a preventive approach. In this lamps are replaced to ensure a light level when lamps in the area reach 80% of their
Current balancing procedure
Thick over all possible combinations of phase load changes at each 3-phase connection point for either single-phase supplies or loads. When all selections have been made, consider the order in which loads are connected. It is so
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
