Megger Group Limited is a British manufacturer of electronic test equipment and measuring instruments for electrical power applications, best known for its original electrical insulation testers. The company traces its origins to 1889, when Sydney Evershed invented the first portable insulation tester, and the Megger name was registered as a trademark in 1903. Today the company operates globally, serving utility, industrial and telecommunications customers with portable substation testing equipment and related products. [1] [2]
Design and History
The Megger wordmark consists of the company name in lettering with a red capital “M” and the remaining letters in black, typically set on a white background. [3] The name itself derives from the original “Megaohm meter” instrument, which was branded as “Megger” in 1903. [4] The first trademark for the name Megger was registered in 1903 and remains the intellectual property of the company. [3]
The corporate identity underwent a significant consolidation in 2002. Following a period in which the company operated under the AVO International name, the organization was renamed Megger Group Limited. The change followed detailed market research that revealed the Megger name was more widely recognized than AVO. As part of this rebranding, other legacy brand names including Avo, Biddle and Foster were phased out in favor of a single Megger identity across all products and subsidiaries. [5] [6] [1]
Earlier in the company’s history, the name had changed several times. The original firm, Evershed & Vignoles Limited, was renamed Megger Instruments Limited in 1987, then became AVO Megger Instruments Limited in 1991 after Megger, Biddle and Multi-Amp joined to form AVO International. The group was known as AVO International Holdings Limited in 2000 and AVO International Limited in 2002 before settling on Megger Group Limited later that year. [7]
Meaning and Symbolism
The Megger name is a portmanteau derived from “megohm” (one million ohms) and “meter,” referring to the insulation resistance measurements performed by the company’s original 1889 instrument. The name became so closely associated with insulation testing that it entered electrical engineering usage as a generic term for such devices. [4] The company actively protects the trademark, noting that it is incorrect to use the word “Megger” as a verb, noun or in the plural form, and that such use is illegal when referring to products not made by the Megger Group or its subsidiaries. [7]
Typography and Design
The current Megger logo is a wordmark-only design with no accompanying symbol or icon. The red capital “M” followed by black lowercase letters creates the distinctive two-tone appearance of the brand name on white backgrounds. [3] No official documentation has been located identifying a specific designer, agency or typographic specification for the current wordmark, and the exact date of its introduction is not publicly documented.
