Product & Technology News
- The distribution transformer  is the last major equipment in the power supply chain and is supposed  to work at all times to ensure continuous power supply to consumers. The failure of a transformer disrupts power supply to all the consumers fed by it and results in inconvenience to consumers.Â
- Even after repairs when back in service they are re-exposed to work under same conditions risking repeated failures. Owners of distribution Transformers incurr huge cost of repair and loss of revenue for the period of outages in addition to loss of reputation. On the other hand consumers are greatly inconvenienced during the period of outages.
- Causes for the failure of distribution transformer: The excessive rise in the operating temperature is the main cause for transformer failure. Various standards such as IEC, BIS, and BS have specified the operating characteristics for transformers. These are known as “Thermal characteristics†and are typically specified for both hot and cold working conditions of the transformers. The thermal time constant which determines the time required to rise the temperature of the transformer depends on its size, weight and rating.
- The loading of the distribution transformer varies from light load to overload. The duration of over load may be continuous or cyclic. Again the loading pattern also varies during the time of the day, season of the year and nature of the load. Continuous changes in the internal temperature of the transformer will result in thermal stress on the internal insulation leading to progressive degradation  of  its  property.  Excessive operating temperature for extended duration will lead to burn out of insulation resulting in transformer failure.’
- Avoids transformer failures and improve transformer management : To avoid distribution transformer  burn-out,  it  is  necessary  to  ensure  its  efficient  and  safe  working at all times. The patented design of SMARTCON—DT ensures that various causes that are determinental to the safe working of the transformers  are adequately  addressed  to guarantee,  years  of trouble free performance of distribution transformers. SMARTCON—DT also enables excellent management  and control by measuring, Storing & Communicating  various  performance  parameters  of the distribution transformers.
- Its features include: Setting of SMARTCON is extremely simple; multi-level password protection and tamper proof design; 2-way communication through communication port and GSM/GPRS network for distribution automation; protection against over current phenomenon; protection against over load phenomenon; protection against undesirable voltage; auto-reclose following over load; auto-reclose after bus voltage stabilizes; alarm indication to detect phase sequence reversal; integrated control for power factor improvement (optional) ; real time display of line voltages, currents and power factor; exhaustive fault and event records facility; exhaustive load flow data to analyze the loading pattern.
