How to test a surge protector (SPD) using a Metrel Mi 3152

Показать описание
How can you tell if a surge protector will function correctly?

With the 18th edition of BS7671 surge protection devices are becoming more common in electrical installations. In this video, we explore how you can test an SPD to check it will function to the manufacturer's specifications.

We use a Metrel Mi3152 multifunction tester which has a dedicated surge protector test function.

Learn about the Uc value of surge protection devices, as we test type 2 SPD's within a Lewden consumer unit and separate Wylex unit design to fit in meter tails.

Testing of SPD's isn't a requirement of BS7671 as part of initial verification or and EICR. So the test shown here should be considered a functional test.

Great demo as usual. One small note, most colleges will tech that for insulation resistance testing (where a voltage above 50v dc is being applied) is subject to the recommendations of GS38 with regard to leads and probes. This is backed up by GN3 1.1 Page 12.

Been testing SPD with My metrel 3101 for years. Nice video btw. Stay safe and stay Home. With love from Denmark.🇩🇰

Muito bom, eu ainda não tinha visto nenhum equipamento que fazia teste em varistor. Poderiam tiram duas dúvidas, o ensaio é realizado com o circuito alimentado ou desligado? Esse ensaio é apenas para o Classe-II ou pode ser feito para os Classe I e I+II onde (I) geralmente é um centelhador à gás. Obrigado ...

Nice vid, . I am lookin into forms on p158-159 of Guide not 3 they tested SPD at 250, I wonder to know what voltage applied? Could you please make a video to show haw value in pages 158- 159 of guide note 3, regarding continuty and insulation resistance measured?
Thanks

Hello. A query, what tolerance values ​​could be applied for the Uc of the SPD to compare the Uac obtained in the test?
Will this tolerance data be indicated in IEC 61643-11?
For example DEHN has a value tolerance table for its SPDs
Cheers

Wow that’s is very interesting .
Always wondered if theses things can be tested, would it be the same for AFDs ?
Fantastic video guy’s as always 👍👍👍❤️⚡️

Great video again.
In the second spd the measurement passes through the varistor on the live and the gdt on the neutral side, correct?
Are these tests non-destructive to the spds?

Do you know if the megger MFT has the same feature?

Very well presented video, thanks guys. Couldn't help but notice the 3x circular cables passing through the same stuffing gland... decidedly un-british if you ask me :-)

Hi there... I wonder, for domestic power supply system of AC 240V, wouldn't Uc = 275 V still can bring damage to the load in house?

Nice video, can we do this test with Magger MFT ?

Can we connect output of type 2 spd to neutral instead of earth?

Hola saludos desde argentina. Tengo el instrumento MI 3152 XC. Realizado ensayos con el localizador R10k para localizar conductores o cables? Saludos

For those of us who do not own one of these all singing and dancing mft’s, could a standard insulation resistance tester be used to test below the uc value and again above the uc value. (Eg @ 250vdc then again @ 500vdc) then we would expect an infinite reading at 250v, and a short at 500v between line and neutral?

Not sure there will be a surge of people testing these outside the factory. 😄 great demonstration of how though. 👍

Nice very informative video but maybe in the future the SPD should be incorporated in the DNO Master Switch module so therefore becoming the District Network Operator's responsibility and standard fit for new and modified installations
