"A Lightning Arrester, Surge arrester or Line arrester is a device used on electrical power systems and telecommunications systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical Lightning Arrester has a high-voltage terminal and a ground terminal. When a lightning surge (or switching surge) travels along the power line to the Arrester, the current from the surge is diverted through the Arrestor, in most cases to the earth. If protection fails or is absent, lightning that strikes the electrical system introduces 1000 of kilo Volts that may damage the transmission lines, and can also cause severe damage to transformers and other electrical or electronic devices. Lightning-produced extreme voltage spikes in incoming power lines can also damage electrical home appliances that’s why it is damn crucial to check the integrity of Lightning Arrester.

"General Electric Company (GE) was an American multinational conglomerate founded in 1892, incorporated in the state of New York and headquartered in Boston. During 1889, Thomas Edison (1847–1931) had business interests in many electricity-related companies, including Edison Lamp Company, a lamp manufacturer in East Newark, New Jersey; Edison Machine Works, a manufacturer of dynamos and large electric motors in Schenectady, New York; Bergmann & Company, a manufacturer of electric lighting fixtures, sockets, and other electric lighting devices; and Edison Electric Light Company, the patent-holding company and financial arm for Edison's lighting experiments, backed by J. P. Morgan (1837–1913) and the Vanderbilt family. Henry Villard, a long-time Edison supporter and investor, proposed to consolidate all of these business interests. In 1889, Drexel, Morgan & Co.—a company founded by J. P. Morgan and Anthony J. Drexel—financed Edison's research and helped merge several of Edison's separate companies under one corporation, forming Edison General Electric Company, which was incorporated in New York on April 24, 1889. General Electric was formed through the 1892 merger of Edison General Electric Company and Thomson-Houston Electric Company with the support of Drexel, Morgan & Co. The General Electric business was incorporated in New York, with the Schenectady plant used as headquarters for many years thereafter. Over the years, the company had multiple divisions, including aerospace, energy, healthcare, lighting, locomotives, appliances, and finance." (Source: Wikipedia)
