Further, the path wasn’t easy. Field challenges were hard nuts to crack. “It was difficult to get the system functioning in wet areas. There are lizards and rats in the panels. Further, 440V 3-phase wiring is very open and susceptible to shock hazards. Sparks in the starters of higher-HP motors could create a nuisance to automation systems. Voltage range is also extreme, i.e., single-phase 120V to 250V, or 3-phase 250V to 500V,” says Ostwal.
Ossian Agro Automation had to take great care in designing the basic transformer to withstand high stresses at high voltage conditions. “Transient protectors like MOV and RFI filters were used in the primary side of the transformer. The capacitors we used could withstand high voltages. We also chose ICs that had tolerance levels of 5-12 volts and introduced 0.1µF disk capacitors at places in the circuits. Overall, the circuit was designed in such a way that the load current extracted was the lowest, reducing the heat generated by the system,” says Ostwal.
In the future!
Looking ahead, Ostwal believes Nano Ganesh technology could be used in controlling any electrical appliance. “Street lights and neon signboards, fountains and waterfalls, air-conditioners, industrial heaters or security systems—Nano Ganesh technology can be the remote to control them all,” says Ostwal. Thus it is only a matter of time before mobiles become remote controls for life management. A mobile unlocking your door or opening your garage might just be on its way!
