Elsco Transformers reports that choosing the right transformer size involves calculating kVA based on voltage and current for ...
Abstract: Excitation power provision is crucial for the operation of wound-field synchronous machines. Modern excitation systems are predominantly brushless, comprising an additional machine called ...
Abstract: In modern substations, some impinging transient surges may coincide with a power transformer's natural frequencies. This can cause considerable voltage building-up inside the transformer ...
