Single-phase Distribution Transformer accepts single-phase AC power and output single-phase AC power, typically at a higher or lower voltage level.
Single Phase Distribution Transformer is a type of power transformer that utilizes single-phase alternating current, meaning the Single Phase Distribution board relies on a voltage cycle that operates in a unified time phase. The ratio of primary (input) windings to secondary (output) windings determines the change in current. Single-phase transformers with a 1:1 ratio can be used to isolate circuits. Single-phase transformers abide by Ohm’s law, and outside of minor inherent loss due to heat, do not create or remove power.
They are often used to step-down long distance and localized transmission currents into power levels more suitable for residential and light-commercial applications.
|Operating frequency range||Transformers with high operating frequencies tend to be smaller, as fewer windings are needed to match impedances.|
|Primary voltage rating||Input voltage range; several nominal voltages represent more than one primary winding.|
|Secondary voltage rating||Output voltage range|
|Secondary current rating||Rated output current|
|Power rating (VA)||Maximum voltage suitable for a transformer, expressed in volts-amps.|
|Operating temperature||Safe temperature range of a transformer in operation; transformer temperatures rise while in use.|
|Current limiting protection||An overcurrent protection mechanism.|
|Flameproof||The transformer has enhanced fire resistance, which is useful in potentially-reactive environments such as mines.|
|NEMA enclosure||The transformer casing or container conforms to a NEMA rating, a standard regarding ingress protection for various industrial and environmental contaminants.|
|Indoor/outdoor rated||The transformer is specified for certain operating environments. Oil-filled transformers are almost always installed outside.|
|Waterproof||Transformer has a sealed case to prevent water intrusion.|
|Submersible||Transformer can be submerged.|
|Tamperproof||The transformer cabinet retains a lock or other vandal-resistant mechanism.|
