“With Surge Protection Devices (SPD) becoming increasingly common in installations, it is surely time that there was an accepted test to confirm their efficacy,” says Brendan Beaver, manager of Metrel UK, a manufacturer of innovative test solutions.
“The manufacturers say that they are 100% tested before they leave the factory, but it is not hugely reassuring to the installer whose insurance take on liability once they supply and install the SPD.
“Metrel multi-function testers have for more than 10 years offered a ramp facility on the insulation test which gives the ability to test varistors and some SPDs in the field.
“Maybe it is time that the powers that be recommend a test protocol which could be incorporated in all multi-function testers.”
