Brendan Beaver, the manager of Metrel UK Ltd said, "With Surge Protection Devices (SPD) becoming increasingly common in installations it is surely time that there was an accepted test to confirm their efficacy." "The manufacturers say that they are 100 per cent 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. Furthermore we know they deteriorate with repeated overvoltage episodes; so how should it be tested as it ages? We know that electrical engineers are not going to want to buy the complex and expensive testers the SPD industry sells. They are going to want an additional function on their existing tester".
