TESCO – The Eastern Specialty Company was founded in 1904 by a metering engineer at the Philadelphia Electric Company (PECO) who saw a need for safer products in the industry and designed the first meter test switch to promote safer field operations. TESCO also designed the first load boxes and transformer burden test equipment, and became the industry standard for electric meter testing throughout the 20th century. Utilities all across North America have used and relied on TESCO products for 117 years.
Any meter test technician or engineer knows the TESCO name means reliability and ruggedness. This reputation for durability continues today with our commitment to develop and deliver artificial loads and burdens, test switches, wattmeter test accessories and a full range of meter testing operational support needed in today’s competitive and changing market.
