Power Outage In Frankfurt Area (Germany) - And People That Need A Breathing Ventilator

I just read that in the western part of the city Frankfurt (Main, Germany) the electric power was down for more than 10,000 customers. A current transformer (CT, for measuring the current) blow up ... and produced a lot of smoke. The power went off from 17:15 on Tuesday 2021-10-26. The restoration took some eight hours!

The Hessenschau (de) reported that nine (9!) people that depend on breathing ventilators had been hospitalized. This critical situation tells us, that the ventilators did likely not have battery backup power - either in the devices or external. The devices we use for my wife have both two internal batteries which give (rated!) power for 16 hours for each device.

This brings two questions up in my mind:

1. Why is it not required by law that all breathing ventilators have battery power for at least 24 hours?
2. Why don't we have to have external batteries and inverters that would give power for several days?

Instead of bringing patients with the ambulances to the hospital, it would be much easier (faster and cheaper) to bring an emergency power supply package (batterie plus inverter) to the patients! Or?

There seems to be a wide area of improving the quality of life.

By the way, why did the CT (current transformer) crash? Was it too old or not ... or? I hope that my friend Andrea Bonetti (one of the most experienced protection engineers on this planet) will comment on the importance of CTs!

Any comment?

Add on (2021-10-30): 

First: The utility has told that more than 100 workers are involved in fixing the problem ... the current fix is provisionary only! 100+ workers means: It must be a big problem that needs so many people to fix. 

Second: It was reported that in an elderly care home the nurses had to use their mobile phone's flash light to look for the elderly people ... no emergency light! Hmm ... strange. A few 12V batteries and some 12V LEDs would have done a good job! Cheap and useful ... lifesaving! ... if somebody would care for their maintenance. The management has obviously decided to purchase a hand lamp per floor ... 👍 something is better than nothing. Note: A battery leak (AA or AAA batteries) may damage a flash light that is not used often ... or only in case of emergency. Non leaking batteries are available: Lithium Batteries are the right choice for emergency devices. I have replaced the typical AA and AAA batteries with Lithium batteries for all flashlights and outdoor devices like thermometer ... they withstand cold weather and do not leak ... life time likely 10+ years ...

Some Information About My Personal Situation

You may be surprised about the fact that I posted very few information on this blog for some time. Let me explain our family situation here at home. I received an email today from a colleague and follower of this blog. This email encouraged me to publish excerpts from the emails we exchanged and to add some thoughts at the end of this post:

Email I received on 2021-10-16:

"Dear Karlheinz,

Perhaps you remember me, I've long been a keen follower of your blog on IEC 61850, and we have exchanged e-mails a few times in the past. ... I am writing to you because 

I remain looking forward to any news from you ... Kind Regards ..."

Email I sent on 2021-10-16:

"Dear ...,

I am sorry to read these lines ... 

I have changed my work (now being retired) to nurse my wife 24/7 … she was diagnosed ALS in January 2017. We are happy that the Lord Jesus has helped us to do that work together with one of our daughters. My wife needs non-invasive ventilation around the clock … we are still together … which is very good.

So, as a consequence I have more or less stopped my business …

Have a great weekend!

Best Regards,
Karlheinz"

Email I received on 2021-10-24:

"Dear Karlheinz,

I am very sorry to learn that you stopped your business because your wife is seriously ill.

To be honest I had realized that the frequency of your posts had declined in the last months... Your blog was a wonderful source of information and it will be missed by the smart grid community. Your posts were real, technical, relevant, useful stuff and not the usual buzzword-laden, over-hyped bullshit we are all used to read these days.

Given the circumstances, I believe no one will say you didn't do what was your duty.

I wish all the best to you and your family."

Some Thoughts to think about:

• Have you ever thought about the electric power in your personal life or the life of the people around you 👪?
  
  
• What could we do to help keeping the power flow? It is more than IEC 61850 ... 
  
  
• Smart(er) Grids are nice ... more important is the need for power in situations where the public grid is down ... In our case we need power for the breathing ventilator 24/7, power for the lifter to lift my wife from chair to wheel chair ... to bed ... power for the nursing bed (move it up and down), power for light, power for heating and cooking, ... and so on. It is more than emergency power ... we need at least some power 24/7 ... we use just PV, batteries and inverters, ... 
  
  
• Did you know that (in Germany) we had in 2019 some 4,100,000 care-dependent people that needed nursing ... 3,310,000 nursed at home (usually in families), 818,000 in nursing homes, ... even in nursing homes it is not required to have emergency power !! ... some have. What about the many homes that need electric power 24/7 to survive ... I guess most of them believe that there is always power ... except for a few minutes per year ... 
  Click HERE for the source of the German nursing situation.
  
  
• One of the most crucial challenges in the future is to provide permanent available power to those homes that nurse people ... 
  
  
• Try to contact your neighborhood, your police station, nearby hospital, fire station, power utility, ... to figure out how and where you could get power to operate the breathing ventilator or other medical devices in case of a blackout! You may be surprised what you get ... almost nothing.
  
  
• It seems to be more important (or interesting) to install hundreds of super charger stations along the German Autobahn ... than to care about a minimum of power to help care-dependent people to survive.
  
  
• We need all-over more electric storages ... small and big ones ... for various applications ... in order to have electric power whenever and wherever we need some ...
  
  
• Let me know what you think ... or report about your experiences ... Thanks.
