Equipment Protection, Monitoring Electricity


Hi Folks,
I had an amplifier malfunction and the possibility that was proposed to me was that since a transformer blew about a week prior to the malfunction, that I could be experiencing an inconsistent flow of current. In other words and I hope I get this right, neutrality- 90 volts-neutrality 130 volts which would create undo stress on seals and cause a blown capacitor. Yes, weird things were happening with lights and such after the capacitor blew. I live in an apartment and the landlords in this price range are, without exaggerating, worthless. It was just suggested that I keep an eye on my current. Does anyone know what on earth I'm even talking about?
Thanks!

I am not contradicting Elizabeth's advice, which may be right, but if you were really concerned about it, you'd have to hire an electrican and i would think you'd want somebody with experience with commercial ap't buildings- depending on the size and age of the wiring in your building and whether you can even access it (is this a house or a building?), your electrician might be able to poke around a litlte, and take some measurements. Sometimes, intermittent problems don't exhibit themselves- if your voltage is good at the outlet when the guy/girl measures, it may not be at other times. And, perhaps, look into those power regeneration devices. There's a ton of discussion about them here- and they may make sense in an apartment context where you have little control over the AC set up inside. There are also discussions about the relative merits of 'conditioners' and isolation transformers. And remember, none of us have any control over the AC power being delivered to us. That's why all these products.
In ored to understand yourself and make us understand, you should probably mention make/model of amplifier and nature of the problem. Is it audible? Is the amp operational?

If the utility power transformer blew up, yes that could have caused a severe over voltage condition. An excessive over voltage condition will indeed damage electronic equipment.

Check with other tenants in the apartment building and ask them if they experienced any problems from the power outage.

Ok, the electric company said that they show good electricity reading to the meter.

After replacing the bad transformer I would hope so!....

Question should have been, when the old transformer blew, what was the voltage the secondary of the transformer was putting out? Their honest answer? No idea....

File a claim with the power company.... They should pay for the repair of the amp.

I can't disagree with anything that anyone has said. Its ultimately up to me at this point.
Thanks!
G.,
I think that one of these power conditioners might go a long way in addressing your issues:

APC AV H15

or:

Belkin PureAV

Both units provide some of the best surge protection available. Each will provide separate, conditioned power outlets to each of your components and will display discrete real-time current and voltage data.

I think the APC may offer better voltage regulation features which seems important in your case.

I'm fortunate to have good quality power services, and own the Belkin. The emi/rfi filtering seems excellent, programmable power features are first-rate, and the Belkin warranty alone is worth at least the $300 price of the unit, for me. Example: My power service was hit by lightning several years ago, and three of my components were damaged (3 others were not, even though no protector can fully safeguard against lightning, IMO). Belkin was amazing. Within 3 days I received a new PureAV unit, and within three weeks, I received a check for damages.

Both the APC and the Belkin are selling at deep discounts to their $5-600 original prices - very inexpensive for the peace of mind provided.

Good luck, and please post on any solutions you find.
