Power Quality Device

[mshields]

I'm working with a client who has an "electronics" lab. And they've told me that they need the following for power to that space:

1. Noise attenuation (must): both common mode noise, transverse mode noise

2. Transient voltage surge protection (must)

3. Voltage regulation

4. Harmonic mitigation

I wish to provide them all of this with the minimum number of boxes. e.g. the GE Guard III transformers will provide everything listed by voltage regulation. They don't necessarily need a UPS but a UPS would provide voltage regulation and it seems to me if it were to be double conversion type, it would also provide the other things although I'm not sure how well.

Open to suggestion.

Thanks,

Mike

The only way I know of to get all those functions in one box is with a UPS. Any other option is going to take at least 2 different devices, may be more. Depending on the application having a UPS may also provide additional benefits.

A UPS would help but believe that it would not necessarily solve the problem. They probably need an Electrical and potentially an Electronic engineer. They definitely need more than your average electrician or electrical contractor.

Suggest that not all of the circuits feeding the space need this quality. One option would be to have a couple of circuits for the test equipment. Have the power for these circuits feed into a closet where they would locate the conditioning equipment.

These days I think the UPS with true sine wave inverter is probably the way to go.

Back in the olden days I would say a ferro resonant power conditioner and MOV surge protection.

MarkK is on target, for a UPS can get expensive especially with the size battery bank, depending how long the client wants power during an outage. Talk to the client and ask how many circuits he really needs to have those specifications for. Than consult an electrical/electronics engineer. In the past I have worked in several defense facilities with electronic labs and they all require something different for their power requirements.
