Tim Barat liked to be a lineman at an electric company in Australia, where he grew up, even in 2009 in the chaos of the Black Sancher Brush Fire He burned more than 1 million acres and left many without electricity or houses. But when he moved to the United States in 2013, his wife was less excited about continuing the route.
“My wife does not want me to work on high voltage for safety reasons,” Barat told Tech Crunch.
So he went back to school, eventually holding a master’s degree in electrical engineering from UC Berkeley.
But he couldn’t stop thinking about power lines. Or instead, they are listening to them.
“As a human being, we cannot feel the electricity,” said Barat. We can feel it. We can suffer from electricity. ” Although none of them is suitable for long careers. Therefore, instead, the electric company linemen use their other senses to get the handle on what is happening during a closure.
“Generally, we are watching, we are listening. We are shaking the transformers differently, such things. We hit a pole with a hammer and hear how its voice comes, then rings, to tell if it is on the basis of safety reasons.”
This is a diligent and time -consuming process. Utility workers often have to pass dozens of miles to detect the origin of the closure, whether it is a tree branch on a wire, a squirrel that is fried when it made a line, or a line below the strong winds. Only once they report the nature of the problem and the exact location, repair work can begin.

“Some utility spend only nine figures on these patrols,” Barat said.
Barat thought, and he had to be a better way, reflecting his experience as a lineman, he just listened to different pieces of infrastructure. “This is the place where my mind was gone,” he said.
Together with Abdul Rahman bin Omar and Hall Chen, Barat established Gridware. The company’s product is a device that literally hears power problems.
“We think of a grid like a big guitar against the circuit board,” Barat said. “This is a physical thing. We also need to monitor the physical attributes of the grid, not only voltage and current. “
Wires, poles and transformers make different sounds, depending on whether they are hit by tree organs, collided with cars, or are buffed with winds. Gridware sensors, which are riding on the pole exactly below the lines, are not connected to the wires themselves. Instead, they are waiting for mechanical turmoil – sounds and voices – that the company’s AI and signal processing software has been trained to identify the grid as a variety of risks.
Processing occurs on every device, and when the software indicates a potential problem, it sends details and location to the cloud through a cellular or satellite connection (or, if the signal is weak, on another device to relay the message). The whole box is about the size of a member, and it is powered by the solar panel, its base has been given angle so that these panels face the sun. Since they do not touch the power lines and do not require a separate power source, the devices are in a hurry to install: the power lines can be dynamic, and each box takes less than 15 minutes to mount and capable.
Barat said the gridware cash flow was positive last year, but it felt that this was still the right time to raise money. The gridware recently shut down a series of $ 26.4 million under Sequreia, the company specifically told Tech Crunch. Consective Capital, Fifty years, Lower Carbon Capital, and True projects participated in existing investors. “This increase was very easy that we didn’t need it,” he said.
Gridware currently monitors more than 1,000 miles for 18 companies from 10,000 poles to devices. The company had previously worked with PG&E and Kund to ensure that the devices could be informed about the issues in the field.
But before Barat could go to the Utility pole, he needed to prove himself that gridware equipment works.
“I made my grid,” he said. “It is a full size, 55 feet poles, a period of 200 feet, and I spent years in destroying it in any way, shape and shape. I have seen many people how I blow the transformer, throw down trees on power lines, bolt cutters directly with the power lines.
How did his wife feel about it? “I had a problem,” he said, “But he added,” It’s behind us because we are usually getting three to four incidents in the general world. “
