In my country, I took part in design and construction of Auto
Transformer AC Voltage Regulators with automatic control of tap
changing with electromechanical relays.
Since my country is less developing country in Electrical and
Electronics product development, I would like to know if these
Electromechanical Relay Type-Automativ AC Voltage Regulators with Auto
Transformers are obselete or not.
Are they still required for certain applications?
If it is not useful anymore, I would study
solid-state-relay-auto-transformer type regulators, and PWM control
type, Servo motor control type AC regulator designs!
More over I would like to know how to study and analyze relay
connection scheme for such regulators. ( I mean we use up to five SPDT
relays to change six different tapping for auto-transformer to provide
six different turn ratios, one step down, five step up between the ac
input and output. I would like to study different combinations of relay
contact points to provide a good voltage regulation scheme)
