When will we get good quality uninterrupted power supply in our country?

[Analogous]

So, apart from installing safeguards in our homes we are giving up on demanding reliable and clean supply from the provider?

I still hope the system can and will improve. It’s just that they have never been challenged to do better. The salaried bureaucrats wait for elected politicians to order and resource necessary changes.

Maybe it’s not a priority for some consumers, but if a large enough group requests….we have after all witnessed the effectiveness of mobs in other aspects of life over the past two decades. For elected politicians to act, It’s all down to voter numbers demanding this.

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)

So this is installed in the meter room for each flat?

Yes at least in my society in a common meter room per block

Any idea from where it can be purchased?

Seems some states use 240v and other 230v. Some discussion was happening within govt to shift to 230v. Just from Google.

I think only reason for private players to be interested in playing 240v as it inflates bills a little without any effort. As usual govt and business run together so no one to take care of aam aadmi especially audiophiles who do MRI scans of electricity in their homes and then treat it with various therapies before feeding out beloved machines

My experience, in my home town we used to get 130v normally with huge fluctuations to 230v entire day. This was few years back and I remember the step up transformer has a buzzer alarm for turning down the manual knob once the output crossed 240v on analog meter. Those were the days. Still nothing fried. Only negative experience was when lightning struck one night that resulted in burning of the computer surge protector (while main switch was off !) moral of story is that it will happen when it will happen nothing can stop it.

This is welcome news. But it looks like Maharashtra will not change. They have 8 lacs transformers without a tap for 230v.

Chief Engineer (Testing), MSEDCL (Maharashtra) informed that they are following 240 V supply voltage. They have a Transformer fleet of nearly 8L DTs. No tap-changing facility is available at DT level, though it is available at higher level. He further informed that the secondary side voltage of Distribution Transformers in Maharashtra is 433V / 250 V. Incase 230 V Declared Supply Voltage is to be adopted, then all DTs needs to be changed which will have huge financial implications.

Yes. If your flat has automatic generator backup that kicks in when the main electricity goes, then your building too will have this ACCL. Just ask your society secretary for the make of the ACCL. These ACCL lasts for around 4-5 years. I have replaced it twice since 2010. My current ACCL is from vguard. Earlier one was from Havels which didn't last very long. But none of my ACCL had the high voltage cutout. These ACCLs are available in any electrical shop in the city.

Mbhangui, I live in Mumbai. We guys don’t have generator back up. I have generally never faced any problem vis a vis electric supply.

Then that amic device is what you can put. It has adjustable low/high voltage cutoff and also the recovery and action time settings.

Do these guys also have just a voltage cut off device?

There are few which are pure voltage cutoff (without any voltmeter). Here is one with Over-Voltage Protection: Adjustable range from 230V to 300V (default setting: 260V).

There are two models. One with adjustable voltages and one without. So be careful when buying. The adjustable one looks like this

I would want something at the main board for a single phase. The Amicismart seems a better option.

Any idea what technology is it using to ensure voltage cut off and overload protection?

Hi Prem,
From the specs I cannot determine if the high voltage cutoff is adjustable. It seems that it is fixed at 280 volts.

They all use a microcontroller to sense the voltage and power off a relay to cut out the supply.

SMR seems unique idea thanks, but wouldn't Solar charged battery power wouldn't be more practical, I'm Noob on this kindly someone enlighten us as its easily doable.

The SMR bit is a joke.
Yes, solar, lots of batteries is your way to go. Except that when there isn't enough sunshine on those gloomy, rainy days, you'll need some grid support.

Is this true?
How does it help the supplier make more money?
