We are lucky here, most power outages are caused by trees falling across the lines, power just goes completely... Between 6 hours to a week when a storm goes through...
Generators are a must this time of year, or like a friend has done, off grid, rarely has a power issue that way...
Brown outs do the most damage, but a spike can be just as bad...
Brownouts can have many causes, including damage and getting off the Hertz balance.
Brownouts are all to do with voltage - nothing to do with frequency. The frequency of the supply will only dip when a massive load is applied to the generator(s) - usually when one source of supply fails and leaves what's left unable to cope - it would only last a few seconds before the underfrequency protection would trip the other sources of supply - leaving a blackout.Quote:

No. Genny has twin outlets. So I put it near the water pump for one and a long lead into a power board inside the house for fridge and telly.Quote:

I have 2x 3kva gensets that I keep topped up with fuel and it only takes a few minutes to run some leads and power boards into the house to keep the freezers/fridges running and the TV for the essential Home and Away for the missus.
In the office I simply run an ark pack and small inverter.
Just about every time we get a Summer storm or some other nasty weather we generally loose power and I have usually already set up the gensets before the lights go out because it happens that often.
Dave,
We had the blackout for a minute or two, but no brown out.
Re the TV continuing to work, most electronics/computers these days have an operating voltage of 110V-250V. This is to simplify manufacture and keep parts to a minimum so the same device and be manufactured and sold to markets around the world that have differing supplies (110V/50Hz, 240V/60Hz etc). You'll see the input power specs printed on a sticker or embossed on the device (or power pack).
