History and Evolution
Megger’s origin story begins in 1889 when Sydney Evershed invented the first portable electrical insulation resistance tester for the London Electric Supply Corporation. The device—combining “megohm” and “ohm”—became so synonymous with insulation testing that “megger” entered electrical engineering vernacular as a generic term. The company formalized as Evershed & Vignoles, later becoming Megger Instruments Limited and eventually Megger Group Limited through various acquisitions and restructurings.
Throughout the 20th century, Megger expanded beyond insulation testing to manufacture comprehensive electrical test equipment including cable fault locators, earth ground testers, power quality analyzers, and transformer testing systems. The company operates manufacturing facilities across North America, Europe, and Asia, serving utility companies, industrial maintenance departments, and telecommunications providers. Megger has maintained its position as an industry standard through continuous innovation in portable test equipment technology while honoring its 130+ year heritage as the original insulation tester manufacturer.
Typography and Design
The Megger wordmark employs a bold, sans-serif typeface with strong geometric letterforms that convey technical precision and industrial durability. The uppercase letters feature consistent stroke weights and slightly squared terminals, creating a contemporary yet authoritative appearance. The primary red (#FF0000) set against dark charcoal (#231F20) or reversed to white (#FFFFFF) provides maximum contrast for visibility on equipment faceplates, carrying cases, and safety documentation. The typography’s straightforward construction reflects the brand’s commitment to clarity and functionality—essential attributes when electrical professionals rely on Megger instruments for safety-critical measurements in hazardous environments.
