RuncoN (A Brand Of Maurya Enterprises)

Switching of Electrical Equipments in industrial and commercial Generates spikes up to 10000 Volts and high frequency Noises thus disturbing the sine wave output. The spikes can cause the failure of Thyristor, Microprocessor or other sensitive devices.

The High frequency noise can interface with digital – Electronic Equipments Causing data corruption erratic behaviors, loss of memories etc…

Isolation Transformer eliminate such noises and attenuates the spikes to minimal values, providing complete protection against such electrical disturbances. It consists of double wound Transformers with Extremely low coupling capacitance to isolate the voltage spikes and reduce noise from mains with extremely high insulation resistance. The turn ratio of Isolation transformer is 1:1. It is generally installed with the separate machines.

RuncoN distribution transformer is a type of transformer used in the final stage of power delivery—it reduces medium voltage from the distribution network to a level that can be safely used by homes and businesses.________________________________________⚡ What a Distribution Transformer DoesIt typically converts:• 11 kV / 33 kV → 415 V (3-phase)• 415 V → 230 V (single-phase for homes)This is the last step before electricity reaches consumers.________________________________________⚙️ How It Works (Simple)It operates on electromagnetic induction:• AC supply in the primary winding creates a magnetic field• This field induces voltage in the secondary winding• Output voltage depends on the turns ratio________________________________________�� Main Parts• Core – magnetic path (laminated steel)• Primary winding – high voltage input• Secondary winding – low voltage output• Transformer oil – cooling + insulation• Tank – houses all components• Bushings – terminals for connection• Breather – keeps moisture out________________________________________�� Types• Pole-mounted transformer – seen on electric poles (rural/urban)• Pad-mounted transformer – ground-mounted (cities, underground cables)• Single-phase• Three-phase________________________________________�� Typical Ratings• 25 kVA to 2500 kVA• Voltage: 11 kV / 33 kV primary → 415 V secondary• Frequency: 50 Hz (India)________________________________________�� Key Characteristics• Designed for continuous operation (24/7)• High efficiency at low load• Low core losses (important because it's always ON)________________________________________⚡ Power Flow Example1. Power comes from substation at 11 kV2. Distribution transformer steps it down3. Output becomes 415 V (3-phase)4. Homes receive 230 V (single-phase)
