Power Outages, what you need to know!

We have all had them, Power Outages, inconvenient, and also very deadly, well to Electronic equipment anyway. You see when any Circuit, is Made or Broken, at the instant of contact, when reconnecting, the current draw is considerable, also, after the connection has been made, and the "Load" being connected, and the Current draw is large, all sorts of transients, Spikes, Surges, Oscillations, is reflected, up and down the entire network. Now along with this, MOST people do NOT completely remove, the unit from the mains, by withdrawing the plug. nor, probably, even turn it off. This is wrong, ALL/ANY electronic equipment, that is connected to that Grid, will also encounter a phenomenon know as "Inrush Current" Now, this Inrush Current, Can and Does cause a great deal of damage to electronic equipment, the, instant reconnection, without going through an ON/OFF switch, and Power Conditioning Circuitry, well, the initial Current draw for that instant, is incredibly, high, and with nothing between, the current surges in, stressing everything, in the Power Supply, and more. Now along with that, you also have Transients, Spikes, Surges, Ringing, Oscillations, caused by the reconnecting of the Circuits. Joining of Cables, or Contacts. When the Power Goes OFF, you should NEVER leave anything plugged in after a Power outage, you need to withdraw each and every plug, from ALL Electronic equipment, note here, purely resistive, and relay type equipment is usually immune, it must be removed, and it shouldn't be reconnected, until about 5 minutes, AFTER the Power has been reconnected. This is to Avoid, all of the bad things that are caused by the reconnection back onto the Grid. If you do this, you can be assured of you Electronic items, lasting at least as long as they should, and not suffer premature deaths.

After 3 power outages and thunderstorms TV quit working as well as PS3, I replaced the power source in Tv,still won't turn on.


Some circuit were blown up by power surge. You should use your electronic equipment with power regulator.

Why are we more dependent on power quality sensitive services?


Electrical power users are these days more concerned about quality and reliability of power supplies for critical operations. These concerns were to the fore in the recent power outages due to storms. Modern electronic equipment is also susceptible to voltage sags, swells, transients and distortion prevalent on many power circuits. Industrial sites experience more serious disturbances than commercial and residential sites, due to the negative impact of machinery and equipment on load power quality.

DEAD TV


A lot of problems can cause "Dead TV"
1. Check power cable.
2. Check fuse.
3. Check the power supply section. You can check the secondary output voltages to confirm the power supply status.
4. Check the inverter circuit.

These are some common problems that can lead to a dead set.

if you not an electronic technician please know that there is a danger of electric shock with these equipments as voltages can be very high. Consult a professional.

All the best.

Dimmer Switch not working after power outage


It's quite probable these units have gone faulty, due to the "Outage" see my previous post below.. You will need to replace these units, to restore functions.

We had a power outage. TV and video both now dead. Changes fuses in plugs, still dead. Could the fuses in the appliances be blown ?


HELLO

Power outages can damage electronic items!

It is certain that the fuses in each of the units power supplies will be blown but I would recommend that you get both in for servicing as sometimes changing the fuses INSIDE and trying them again CAN cause more damage - and more cost to repair.

Better to be safe than sorry! (:-)
