Intrans make Outdoor metering cubilcle consists of two Current Transformers and One Potential Transformers along with Test Terminal block and Fuses enclosed in a powder coated Galvanised Iron Enclosure confirming to IP54 Standards.

Intrans CSS consists of Oil filled Transformer with HT and LT switchgear. The transformer is of Corrugated tank type of construction and Hermetically sealed. High Tension side of the CSS consists of Load Break Switch or Vacuum Circuit Breaker as required. On the Low voltage side ACB and MCCBs are provided as per the customer specification. The Compact Sub Station is available for indoor use as well as Outdoor.

Intrans make outdoor load break switch panels comprise of a HV 12 kV Load break switch panel with CT/PT and Test Terminal Block and HT Fuses completely enclosed in a Powder coated Galvanised Iron enclosure confirming to IP 54 Class protection. Even under adverse weather conditions the Galvanised Iron enclosure ensures a long life for the Load break switch.

Intrans manufactures VCBs as standalone type or in multi panel arrangement with future extension provision. The panel contains a draw out type circuit breaker with automatic shelters to ensure isolation from live areas. The panels are manufactured from high quality steel which is powder coated after a seven tank cleaning process to ensure long life. Safety interlocks are provided to prevent accidents.

The USS will comprise of HV 12 KV Load Break Switch Panel, Cast Resin Air Cooled Transformer, with associated protection and Ventilated Housing.The whole assembly is mounted on to a rigid base of steel fabricated section. The units are factory assembled, tested and they will be despatched in dissembled condition. All the dissembled components can be assembled at site.

Load Break Switch is suitable for indoor application and is used to switch ON/OFF the 11 KV supply.The Load Break switch works on the principle of extinguishing the Arc by a blast of compressed air, produced by the switch itself, while opening. During the switch off operation, the Arcing contact maintains continuity while the main contact travels along with the piston attached with it, compressing the air in the pressure cylinder. After a predetermined length of travel, the arcing contact opens striking on arc. At the same time, a blast of compressed air, extinguishes the arc, through the nozzle surrounding the arcing contact.

The Air Break Switch is provided with HT Fuse and earthing facility. The panel is designed to segregate completely incoming and outgoing termination chambers with Epoxy resin cast seal off bushings. The HRC fuses are easily with drawable type so that fuses can be renewed easily. When the fuse switch operates on fault, the mechanism would give simultaneous break on all three phases and also would go into lock position to prevent closure until the blown fuses are replaced. The busbars will be 630 Amps rating, aluminium or electrolytic copper, tinned, supported by epoxy insulators

INTRANS make Oil Test Set is used for testing dielectric strength (BDV) of transformer oil. The electrode assembly and other electrical design features are as per the requirement of IS 335/IS 6792.

The unit consist of a centre tap type high voltage cast resin type transformer which feeds the voltage to the liquid dielectric through the system of electrodes.

To energise the high voltage transformer the inductive potentiometer is used in order to increase the voltage from low values to highest available values. The synchronous motor drives this transformer or can be decoupled. With this arrangement the unit can be motorised or manual operated.

In between the primary of the HV Transformer and energizing networks a contactor and a protective circuit is incorporated as protective and controlling devices. The circuit has fast acting tripping characteristics which gives an ideal protective curve. The contactor acts as main switch and also interconnects safety devices such as door switches, control switches and other allied controls desired by customer.

The output voltage is measured by square front dial instrument. The marking on the dial are Kilovolts indicating the true applied voltage. The circuit is so arranged to have memory effect to breakdown voltage which facilitates the effective operation.

The test cells having dimensions within the limits prescribed by Indian Standards are supplied. The electrode assembly of test cell is strictly in accordance to specifications. The test cell is supported on cast resin transformer terminals and thus brings automatically test sample in HT circuit.

Complete conformation to all the relevant Indian Standard Specifications.

Electronic Meter with TOD (Time-of-Day) metering facility : The meter is versatile enough to register the maximum demand in separate preset periods of the day. With the present control measures this eliminates the need for additional meters for day and for night demand. This can help in planning operations to increase load and reduce average KWH costs. Similar facility regarding active energy consumption at various times of the day is also provided.

Epoxy resin moulded components are intended for use in heavy duty application like high voltage electrical industry wherein high short circuit currents and dynamic forces are anticipated.
