Mobile substation or portable substation is self-contained trailer mounted substation with capacities upto 132 kV. It carries on board HV Equipments | Power Transformer | Auxiliary Transformer | High Voltage and Low Voltage Switchgear | Surge Protection | Several LV Panels | SCADA Panels | Metering Equipment | Relay Panel | Control & Protection Panels | Auxiliary Services Panels | Diesel Generator | AC and DC Auxiliary Power Supply | Telecom Panels | Cooling Equipment | Cable Connecting Arrangement

Protection from lightning induced surges, Protection from secondary faults, Protection from severe overloads, Load management signal light to provide visual warning of overload conditions, Protects the distribution system from a failed transformer, The conventional distribution transformer requires externally mounted protection, such as a fuse cutout and arrester. The Completely Self- Protected (CSP) transformer has this protection built-in, A high-voltage fuse in series with the primary bushing, for protection in the event of an internal failure in the transformer, A Lighting arrester mounted externally on the tank, A circuit breaker on the secondary side to protect it from overloads and short circuits, This feature can be adopted up to 100 kVA rating distribution transformer and beyond externall MCCB can be provided in tamper proof box.Provides protection against short circuit and thermal overloading., Ideal for unattended locations, Ease to operate from the ground.

The earthing transformer is used for limiting earth fault current during earth fault created in the system and simultaneously distribution transformer is used for supplying auxiliary supply of 415 volts for the substation, The values of zero sequence Impedance are specified according to short time neutral current to the fault condition. Auxiliary Transformer is according to the specifications SAN 780 IEC 60076, Auxiliary Transformer is fitted with an Off Circuit tap switch on HV side & housed in common tank, Such ratings up to 500 kVA and up to 34.5 kV.

The design comprises of electrical, mechanical & thermal parameters base on customer specification ISO 9001IEC StandardBSIS Standards.The core is 3 Phase ,Three limb, Five limb or seven limbs, Core duct is provided to limit core Hot Spot. HI-Blaser inscribed sheet steel is choosen as per requirement. Boltless Core is adopted to avoid Hot Spots in Core legs. The InterleavedIntershield DiscHelical Coils are adopted.Standard ribbon width, Use of single grade core material, A sophisticated process of manufacture & transformer cores, right from automatic cutting line & stacking machine, The stack is up righted so that it is resting on edge, The outer lap made to match up & protective sheet is closed with tape to prevent joints from opening.
