When will we get good quality uninterrupted power supply in our country?
- Thread starter Analogous
- Start date
So it is installed at main distribution MCB box , or anywhere where expensive instruments are connected?
No. Surge protector will help you when you have insanely high voltage. It will short causing your house fuse to blow. It would protect your equpments like fridge, ac, etc which takes few seconds to get fried. However sensitive electronic equpments could be toast by then. Once a surge protector activates it is destroyed forever, but that is ok. Now days you get surge protectors that can be installed in your existing distribution box. These surge protectors have indicators when activated and can be replaced just by pulling it out.
Get a high voltage cutout and install it in your existing distribution box. After installation it is important to set the voltage cutout to around 245 volts or so. Have a stabilizer behind your electronic equipment. A servo stabilizer is slow but most of them have a thick windings. Even the AC stabilizers have thick windings. These stabilizer will not conk off so easily under high voltages.
EDIT. These replaceable surge protectors look like this

You have been saved actually multiple times by this accl. Complaining will not help. The electricity board has every right to send you upto 262 volts as per the new voltage standards.

mbhangui, is this the one to get?
mbhangui, if one uses the above, would one still need a surge protector?

Yes. This one supports around 13.8 kW. So you can have around 6 high current devices (ac, washing machine, geyser, oven, etc) running simultaneously, if you are doing to install it in the main distribution box. The other option is to install it in the room which has your precious electronic equipments (especially vintage). You might require the service of an electrician to install it. But installation is very simple. It has two input line and two output line.
Couple of pictures will make more sense to me, if possible and handy? I wanted to understand how to connect it before any instruments, Thanks.
No.
I bought this a few weeks ago. It was just to monitor the voltage and current. I should have waited…the one identified by Prem seems to offer monitoring of voltage and also protect against surges.

As I understand it most power cuts are localised (not every time, but often)
How does this happen at the local sub station?
How is this decided? By whom?
Do these power station officials have complete autonomy in such actions?
Are they accountable for anything? Are they monitored or supervised?
Do they have the means to measure and control power surges?
Or is this all opaque and mysterious?
I am not referring to grid overload and failures.

Yes. Looks like you have understood the thing. Connect the phase to the terminal marked L on the top side of the cutout. Connect the neutral from the main circut to the terminal marked N on the top side of the cutout.
If you have a portable power distribution box, remove the plug. There will be 3 wires. Red, black and green. Connect the Red to the terminal marked L on the bottom of the cutout. Connect the black to the terminal marked N on the bottom of the cutout. Connect the green directly to any earth terminal in the main circuit. Now your portable power distribution box is connected to the safety cutout. Connect any equipment to this portable distribution box.
The other thing you can do is to just break the phase wire in the main circuit box. The input phase goes to the top and the output wire goes to the bottom. The neutral is simplly connected to the top (marked N). So no other thing to change. Your setup remains the same. I think this is what you meant. This is a simple solution as long as you have enough space inside your circuit box to fit this device inside.
@CKumar This explanation to Prem is for you too. I will post my cutout later. (Mine is very different and much older than the above new generation cutouts). The new generation cutouts are versatile.

I have this got 3 years back and so lazy that I have not yet installed it. You have inspired me to install it. This one gives you every possible reading regarding the quality of power. This is a good thing to have.
The one listed by Prem displays only the voltage and current. But it's primary function is cutoff and safety. Your device's primary function is to display the quality of power. It is also a good thing to have

Mbhangui, apart from amicismart which imports from China, there also appear to be other brands. Like Gelco and a few Chinese brands.
Any preferences here? Don’t guys like Schneider or Siemens make these things?

Everyone nowdays replaces the entire unit. In this case they will replace the entire power supply board. No one does component level repair. @sidvee had a similar problem and he got it fixed through a dealer with whom he had a good relationship and nominal cost.
I believe amic is from Taiwan. Most of our semiconductors gets manufactured there. I have not come across these devices from Schneider/Siemens or any one from US/Europe. However there are indian manufacturers making what is called a home protector. These are large iron clad boxes with potentiometers inside which can be adjusted to set the cut off voltage. In one of the reply from @muralimmreddy in this very post, I have come across an Indian brand which can be installed in buildings which have generator backup. It can simply replace the existing accl. These accls are manufactured by companies like L&T, vguard, Havells, etc. I'm going to suggest this device for my society building. This is the device that he posted and it will protect your entire house.
For individual flats. In buildings that have automatic generator backup, there is a device installed called Automatic Source Changeover and Current limiter switch. It is called ACCL in short. These accl switch the output to the generator when the main supply goes off. Every flat has a ACCL switch in the meter room. My building has it. But what has been installed in my building are ACCLs from L&T, Havells and vguard. None of them have high voltage protection. Now this device that Murali posted is a surprise to me. It has over voltage protection. I'm trying to get details of this switch online. If the cutoff voltage is adjustable then this is the best thing. You just have to replace the existing ACCL in the meter room. So far I have not been able to get details. I will write an email to the company and find out
EDIT: Unfortunately it looks like you cannot adjust the high voltage setting. It is factory set (point no 8 below)
