The electrical power grid is particularly vulnerable to these extra currents, which can infiltrate high-voltage transmission lines, causing transformers to overheat and possibly burn out.

相对于这些电流而言，电网极其脆弱。 这些电流混入高压传输线引起变压器过热且可能烧毁。

We take off-the-shelf IT and Internet technology and transform the power grid and electricity transmission lines into an energy Internet.

FORBES: Jeremy Rifkin's Third Industrial Revolution

America's flawed deregulation has left its grid suffering from serious under-investment, which contributed to the recent blackout: transmission lines were old and overloaded, grid computers failed at critical moments, and so on.
