Lightning and surge protection, electrical safety, and test and measurement specialist Surgetek will introduce its thermal imaging power quality analysers, and test and measurement equipment, as well as its new range of surge arresters, at the Power-Gen Africa 2014 exhibition, to be held in Cape Town from March 17 to 19.
Surgetek supplies a range of low- voltage (LV) lightning and surge protection equipment, as well as high-voltage surge arresters, capacitors, voltage-detecting systems, overhead-line fault indicators and safety tools. The new surge arresters were launched on February 19 in Johannesburg.
Most of the company’s power-protection and safety equipment is approved by the South African Bureau of Standards as specified by major companies.
Surgetek’s LV protection divisional manager Paul van As says the surge arresters are used to protect equipment against lightning and overvoltage surges in electrical applications.
The pluggable surge arresters feature Deutsches Institut für Normung rail mounting and visual fault indication, with optional remote contacts, and are pluggable, says van As.
A surge arrester is installed to ensure that voltages remain within the acceptable levels for the connected equipment. The purpose is to divert damaging lightning-induced transients safely to ground through the surge arrester, which offers a low impedance path to earth.
