Unit Sub-Station

OverviewAl asry offers a wide variety of unit substation designs to meet customer requirements. A unit substation consists of one transformerelectrically connected to and coordinated in design with one or more switchgear or switchboard assemblies. A secondary unit substation is defined as a unit substation whose outgoing section is rated below 1000 volts.A Typical Secondary Unit Substation Consists Of Three Sections:Primary: an incoming section that accepts incoming high voltage (2400 to 13,800 volts) lineTransformer: section that transforms incoming voltage down to utilization Voltage (600 volts or lessSecondary: an outgoing section that distributes power to outgoing feeders and provides protection for these Feeders (600 volts and less)Standard Secondary Unit Substations Consist OfMedium Voltage PrimaryTransformerLow Voltage SecondaryAsry also offers low voltage unit substations withLow Voltage PrimaryTransformerLow Voltage SecondaryThe primary reason for using a secondary unit substation is to bring power as close as possible to the center of the loads. Another reason is that it provides a system design concept incorporating a wide variety of components that permits tailoring equipment to the needs of the application.A secondary unit substation provides:Reduced power lossesBetter voltage regulationImproved service continuityIncreased functional flexibilityLower installation costEfficient space utilizationEvery component and assembly of secondary unit substations are designed and engineered as an integral part of a complete system.UNIT SUBSTATION LIGHTING PANELLighting control system are widely use on both indoor and outdoor lighting of commercial, industrial and residential spaces lighting control system serve to provide the right amount of light where and when it is needed lighting control systems are employed to maximize the energy saving form the lighting system. This may include digital timers and photocell that are hardwired to control fixed group of lights independently
