Appliance damage by lightning surge

[crazy_boy]

Ok, so here's what happened. It was raining really hard early this evening and a really strong lightning struck.the damage:

1. Wifi router
2. Wimax modem
3. Panasonic LED tv
4. Media player
5. Soundbar
6. CDR king servo AVR
7. Digital control panel of washing machine is messed up


Unfortunately, 1-3 are completely dead. My dad was watching TV when the lightning struck. 4 & 5 still turns on but couldn't connect/no output. Other TVs at home were spared.

All of those, except the washing machine, were connected to surge protector and servo motor avr. 1&2 were connected together, 3&6, 4&5, and washing machine on its own.


Any advice on what i should do now?

saan po location? are all wiring properly earth grounded?

[crazy_boy]

Manila area sir. Im not 100% sure if properly grounded lahat. How would i know?

From what i've researched last night,possible na may fuse daw sa loob ng tv. So hopefully fuse lang.

As for the soundbar and media player, possible na hdmi ports naman. Sana minor lang.

normally sir may fuse nga na sumasalo sa mga ganyang klaseng scenario (110v plugged to a 220v socket) i just don't know if kinaya nun sa lakas ng kidlat. nakaranas na din ako ganyan. sa pc ko pero ang nasira lang isang ram memory na pinapalitan ko lang at ok na ulit. hopefully tama kayo para mura lang paayos

probably a fuse and a diode burned. kung yun lang, madali lang yun marepair

Malamang hanggang power supply unit ang sira nyan, yung lakas ng voltage surge ay lalampasan nya yung fuse. Lahat ng power adapter ay siguradong sira pero pwede namang palitan. Sana pati yung washing machine nyo ay power supply unit din lang ang kanyang sira.

Lightning came into your house thru the power mains. Report the incident to Meralco at once, let them check distribution for stolen grounding rods/ wires in your area.

As for the appliances, damage will depend on how the electronics were designed to absorb surges. Commonly, power supplies are protected with Varistor that clips overvoltages, but like AVR's and UPS's they are ineffective for lightning without proper earth ground. Static could discharge from elctronic device to the humid air and that fries the sensitive electronics.

To quickly check the earth ground inside your distribution panel, you should be able to measure L-G-N (110-0-110) Line-Ground-Neutral AC Volts, this is for Metro Manila with balanced transmission.

check mo mga fuses ng mga appliances mo baka pumutok lang.kapag sinalpakan mo at pumutok ulit malamang may mga na damaged na mga diodes or protector ,regulator.

nag tataka lang ako kung bakit nasira ung AVR mong CDR-KING

AVR nga diba AUTOMATIC VOLTAGES REGULATOR...


ehehehe ..... cdr-king talaga.

Big headache ba pag power supply ang nasira?

Will report to meralco. Thanks for the tip. Will also ask our electrician to check earth ground.

Actually maganda ang review nung servo motor avr ng cdrking sa pinoydvd. That's why yun kinuha ko.

Nagtanong tanong ako sa neighborhood namin, may isang PC rental store just few hundred meters away from our house, nakuryente pa daw yung ibang naglalaro when the lightning struck.

AVR with servos are slow acting. it takes seconds before the wiper move between the coil. Surges happens in milliseconds.

Still the best protection for overvoltages are MOV(MEtal Oxide Varistors) they clamp at nanoseconds speed. Couple that with gas-discharge fuse and it will clamp more current. Most UPS have this built in that is why they are recommended for electronic appliances than AVRs. Online UPS are the best protection u could get, inverters are ON all the time voltage gets conditioned all the time.

nope...mura lang ang pagawa.

All of my electronics are connected their own ups. Are ups capable of handling lighting surges even if the plug has no 3rd grounding prong?

Lets face it, hindi standard ang 3 prong outlet dito sa pinas, kahit me ground sa bahay namin, outlet is still 2 prong.

It will protect only line-to-line surges. Remember, lightning seeks its path to the nearest earth. The job of the arrester is to divert this discharge path to the ground. If you dont have proper ground it will seek its path to whatever device connected to the ingress media(AC mains, cable or telephone service drop, antennae) every electronics plugged to it is a potential path for discharge point - could be the nearest chasis, a damp floor, or a humid air.

Newer buildings comes grounding as standard. Maybe the outlet isnt but the mains circuit breaker box should have it as a provision if ever you decide to install one. The old house, i had to install ground rods and wires to the powerplant, water pumps & heater, the breaker box, server cabinet, and kitchen electric appliances..

Btw, any recommended repair shop for the TV? Wala akong alam na honest repair shop.

if the house has no provision for a grounding line, it would be safer if i can directly ground the ups by earthing it to metal rod?

[rollyic]

saan ba nangagaling yung lightning surge?
correct me if im wrong, pero di ba galing sa poste ng meralco or cable tv then pumasok sa bahay.
tama po ba?

pwede din direct hit ang bahay.

Wimax modem pinapalitan nang libre diba.

[crazy_boy]

^yes napalitan na wimax modem namin. yung ibang appliance nalang problem ko now

If you are near pasig, there is a panasonic service shop along shaw blvd. They charged me 5,500 to replace the power supply of my plasma TV last year.
