Really depends on the number of over-voltage events it encounters. 2-5 years seems overly aggressive to me for a typical installation with a quality modern strip. I do agree that an auto-shutoff strip is better, especially where the strip is tucked out of view.
Sacrificial (or semi-sacrificial) surge protection is a simple fuseThey come in many designs, but they are functionally simple devices.
Not that I'm any kind of expert but as long as it's a good one then at least it likely isn't doing any harm and potentially cleaning high frequency off the lines which can't be terrible. This paper seems like an intersting primer: https://download.schneider-electric...series-v-parallel.pdf&p_Doc_Ref=SPD-WP-SVPSPD
Ha, I know you say in jest, just like your username is apt for that one!
I'm as stupid as any tube enhanced audio nerd there is and I have no desire to buy this device to improve my audio equipment.
I would also like to add 'surge suppressor'
It's not necessarily cheap if it's meant for effective filtering to a low frequency at high through currents. To give you an idea, I pay maybe $25 for a small industrial EMI/RFI filter assembly from say, Corcom. So the parts must be a few bucks. That would be good for maybe 5A. They get a lot more expensive from there.
That actually was pretty offensive and audiophilophobic. Be respectful to audiophile+ community!
I had a guy, for many years then he got a real job...
| EMI/RFI Filter Response | (bi-directional, wave tracking): With 50 ohm Rg load: 3db at 5kHz; 26dB at 100kHz; 38dB at 300kHz. |
Hehe
I read their copy, I don't see them saying my bootlegs will be so alive I'll be able to smell Jerry's toe jam, just general descriptions that seem to apply to their products generally, but I have no idea what language is used in your industry.
Exactly. Install a surge protector at the breaker box or main panel to protect the entire house and be done with it. They will provide better protection from minor and major spikes/surges. You can for redundancy sake add inexpensive surge protectors on crucial equipment if you care to.
Ruputable companies such as Schneider electric seem to distinguish their series SPD's from parallel SPD's based on the frequency content in the disturbances they they are intended to address. For example this bit of marketting from one of their so called white papers "Benefits of series-connected devices include mitigation of potentially damaging high-frequency noise, a tighter clamping voltage, and performance that is independent of installation practices.". ( I linked this paper several posts back). They go on to compare with parallel devices which are intended for lower frequency high energy surges. Maybe it is not just the laymen using the terminology. Since I'm not an expert, I can only imagine that the spectral content of a bolt of lightning consists mostly higher frequency energy, well above line frequency, and therefore a low pass filter of some topology would make a great tool for the job of snubbing the lightning induced surges for example. Since I cannot find any circuit diagrams of series SPD's I have no idea what is really contained within one. I was kind of hoping you'd have a bit more of a technical response than another appeal to your great authority.
Yes, when you design a surge suppressor the frequency content is a concern. Designs often have resistance and inductance to help limit the current pulses. They will filter, in addition to their main duty. But the point of the circuit is to limit voltage, not discriminate a particular frequency.
