Sentec, based in Cambridge, England, will develop a current sensor that is suitable for installation on 240-600-amp substation mains. The purpose of developing such a current sensor is to reduce the power outage time caused by local grid failure.
According to Sentec, there are now more than 500,000 power substations in the UK, of which only 2% monitor their own power output. In an interview with Electronics Weekly, Sentec CEO Dr. Marc England said: “On average, one substation has a 1MVA transformer connected to the three-phase bus and has five 600A three-phase power cables. Powering hundreds of families."
Each fuse in each power supply cable is equipped with a 600-amp fuse.
England said: "These fuses occasionally blow, but before the user calls the power company, no one knows what happened." This problem makes power companies also feel very troubled because they want to power off for more than three minutes. By monitoring the current of each cable outside the substation, overloaded cables with 15 current sensors can transfer some of the load to other phases or to newly laid cables.
England stated: “Each household may need 80 to 100 amps, so when a few dozen households approach the peak of electricity consumption, a cable will be overloaded.†Together with British-Italian company Celes Galileo, Sentec has developed A monitoring system called the GridKey, which records the current in each cable and the voltage at each stage, sends this data to the power company via GPRS. However, the substation cable has never been installed with a clamp sensor, and some cables have been tightly packed.
England stated: "As more and more sensors are installed, we see that our first-generation sensors can meet 80% of the requirements, and we also need smaller sensors." To develop this more compact sensor, Sentec Join the British Technology Strategy Council for smart power and power distribution, and win an undisclosed amount of money to develop smaller sensors called the Slimsensor. According to England, this task is not a trivial matter.
England said: "This task will be very difficult. The first-generation sensors are already very advanced. This research has certain feasibility. In theory, we are very sure we can develop smaller sensors." Sensors must be passively adapted. For the power system, Sentec's research and development goal is to make Slimsensor consistent with the original version of the sensor. If this is not possible, then in order to adapt to the sensor type, the electronic box of the Sailelix Galileo Company will have to change.
England stated: "We intend to make this kind of sensor plug and play." The project will begin in June this year and will end in April 2013.
