studying the Characteristics and testing, Models of DC Motor, Alernator, Impulse Turbine, DC shunt motor-Generator Set
, DC Power Supply, Measurement of dielectric strength of Transformer oil etc.
He begins with the basics of AC power systems, including their elements and architecture, moving to power generation systems, the power factor, including correction techniques, power transformers, capacitors, semiconductors, rectifier and filter circuits, power electronics, origins of AC line disturbances, power disturbance characterization, protection methods, the motor-generator set
, uninterruptible power systems, power conditioning devices, transient suppression (including at the circuit level and in facility wiring), grounding (practices, tower elements and system design in the facility), standby power systems, designing for tolerance of faults, energy efficiency, safety and protection systems.
The motor-generator set
can also be used with batteries.
His DC-to-AC power conversion method used rotary converters or motor-generator sets
, and some remained in use until recently.
We used to drive high-speed elevators with DC; we converted the building's AC to DC using motor-generator sets
The motor-generator sets
also can still be used for high-power testing.
Kato also manufactures motor-generator sets
and associated controls for power quality problems as well as frequency conversions.
An alternative to rotary motor-generator sets
as a d-c power source.
Predictive Maintenance (PM) is being applied to a wide range of rotating equipment: machine tools, spindles, electric motors, V-belt drives, gear drives, fans and blowers, turbines, motor-generator sets
, and rolling mills.
s Dudhichua and Nigahi mines, will use General Electric motor-generator sets
for powering drag, hoist, and swing motions.
Available at all standard voltage to 600-v AC, sizes range from 10 to 1200 amps/phase and offer an alternative to rotary motor-generator sets
as a DC power source.
Fractional horsepower motors (fractions of one horsepower) account for the majority of motor and generator production; followed by integral horsepower motors (multiples of one horsepower); "prime mover" generators (powered by prime movers like diesel or steam engines); and motor-generator sets
