Could you please make a video for SPD vs volt protection device?

Thanks! I am glad you liked it!

Glad you liked it!

Hey, SPDs connected in parallel, aren't affected by circuit load. Their effectiveness depends on location and the equipment they protect.

I have an electric oven which has a total rating of 28kw, but low voltage tends to disturbs us a lot. As a result, this voltage imbalance most times burn contactors. Would adding an SPD into the installation sort my problem out. If yes, then what size can be suitable. Thanks

​@@DaveSons Voltage imbalance or fluctuation should be addressed using a voltage stabilizer, sized according to your oven's 28kW load. An Type 2 SPD can protect against voltage spikes, but won't solve your low voltage issues.

@@AxisElectrical ❤️. Thanks

Thank you for your suggestion Deepak, we will surely plan something around that topic.

Hi Jagrat, Installing SPD won't result in that, but if SPD undergoes some fault like a short circuit or over current (steady-state faults) it can result in Protective device tripping (RCCB/MCB) so that SPD will be safe and not get burnt. If you want to avoid this risk, SPD needs to be installed prior to the protective device and an additional protective device like a Backup Fuse or MCB need to be installed for the protection of the SPD.

SPD earthing and equipment earthing should be common, and as per the standards all the Earth Pits should be interconnected to achieve Equipotentialisation.

I saw some video where they saying to put earthing of SPD separate from earthing of rest of connection and earthing of lighting arrester also be different, is this correct , please explain

We will try and make a video on that!

Hi Raj, Hum Hindi mei samjaane ke liye, ek separate video par kaam kar rahe hai. Umeed hai aap ko woh pasand aayega!

Thank you, great info.. Also important not to over size spd - e. g. a 1000v spd can not protect equipment with max. 300v input, rather use a 275v so it can protect from 275v spike upwards.
