Rain season finally has arrived with a lot of thunder and lightening and

as always I am concerned about my computer hardware.

Is it useful to have an extra surge protection connected to a UPS or

will the UPS alone do the job?

any (brand) recommendations are appreciated.

Lightning Protection: (my old replay)

First question is where we have high Voltage by Thunderstorm Lightning.

This is between Phone line and Power line, except see below.

To protect Computer and Modem it’s necessarily to eliminate this high Voltage.

UPS with Phone line protection use ZNR (allow only pass voltage up to about 300 Volt) and 2 Resistors (most 10 Ohm) in the Phone line. The ZNR limit the Voltage between Phone-, power line an Ground. If lightning stroke, the 2 Resistors can blow out and must be replaced, bud PC and Modem will be intact. (I’m replaced already 3 times).

Not all UPS (uninterruptible power supply) support real Protection (Leonics and APC will be OK). Most Notebook PC’s today have W-Lan integrated and with a W-Lan Modem (ADSL, e.g. D-Link G604T) and wireless, the loop between Phone and Power line not exist (recommended). Worst case the modem blow out, bud the modem is much cheaper as Notebook repair.

Except the Lightning strike near (about 5 meter) or direct in house.

15 years ago the Lightning stroke in the water tower near my house. Result:

Shortwave Antenna no more exist, Shortwave Receiver, Modem, SCSI Interfaces, PC, Stereo, TV’s, Phones, Fluorescent Lights destroyed.

Refrigerators and Aircons are still OK. In this case it’s impossible to protect. Even a piece of unconnected wire has high voltage.

webfact - A good quality UPS should provide sufficient protection. However. should you have a direct hit or nearby lightening strike, no UPS or surge protector can handle that extreme level of voltage and current. In such a situation, unplugging sensitive equipment/appliances is your best precaution.

Waldwolf, thanks a lot. These links helped me very much!

Everything they say ^^^^

I won't buy any UPS brand other than APC, not cheap, but regarded as THE manufacturer. Adding an extra, good quality, phone line arrestor is belt and braces insurance.

Also, it is vital that you have a decent ground connection for the surge arrestors to work correctly.

Not any UPS orSurge Protector works correctly or anyway without propper grounding GROUNDING IS A MUST!
