Eskom Loadshedding Solutions - Prevent equipment damage in your Home and Amateur Radio Shack when power returns after an Eskom load shedding period.

GENERAL WARNING: Never undertake a DIY electrical task or any other modification to you home if you're not qualified/certified to work on home electricity systems or when your home is insured. Always contact your insurance company and discuss your undertaking with the company. If you do not you will find out the hard way that the company will not cover you house or property if a disaster of some kind occurs. Ensure that you obtain the necessary permission and any certificates required. You have been warned!!

In a follow up to the article "Load shedding killed my Home Network Router? How to prevent this from happening to other equipment in future!"  my son and I decided to prevent this from happening again. He is a fully qualified electrical engineer and has all the qualifications/certificates to work and certify any electrical low and high voltage undertaking.  With 17 years service and currently a Senior Superintendent I was confident that he could easily come up with a project that will protect household equipment.

He decided to construct a  220v Time Delay Switching Unit that control the power feed at the electrical distribution board when power return after an Eskom load shedding period.  This unit had to be robust/safe and must fully protect household electrical equipment.  Therefor a small relay circuit would not perform the task we had in mind. 

My son decided to use the following components for the project:

• 230v Avanti Multi Function Timer  11 Pin
• Timer Square 11 Pin Base
  
• 45 Amp Electrical Contactor
• 230v Green LED Pilot Light
• 230v Red LED Pilot Light
• 230v LED Compact Voltage Meter
• 220v LED Compact Amp Meter
• Cable House Wire 6.00mm Black
• Cable House Wire 6.00mm White
• Metal Din Rail for Circuit Breakers
• Major Tech Electrical Enclosure/Cabinet 350x300x130mm
• Circuit Breaker for additional protection even though the unit also runs through the Earth Leakage Circuit Breaker 

I am not going to go into building detail as this might entice non qualified DIY enthusiasts to illegally construct and install such a build.  See General Warning above.

Here is a bit of theory regarding the build:

A timer delay/relay

A timer delay switching unit has a timing element device that intentionally delays the switching ON/OFF of power flow immediately once the power is applied or removed from the contactor.  A time delay has an inbuilt time delay function, so the contactor will not activate immediately once it is activated although it will wait for a fixed amount of time.

So this kind of “relay” is applicable where delays are required before the contactor activates like security systems, industrial automation and now power supply return after Eskom Load shedding.

A Contactor

A contactor is an electromechanical control device that used to make or break the connection between the load and power supply. The use of a contactor is similar to the relay. But the device used for higher current carrying application is known as a contactor and the device used for lower current applications is known as Relay.

A contactor has several contacts as per the application and load. Generally, these contacts are normally open (NO) contact. And hence the load is shut off when the coil of the contactor is de-energized. But the contactor can design for both normally open and normally close applications. The most common application of contactor is in the starter that used to turn ON and OFF the equipment like motor, transformer, etc.

A contactor is an electrically controlled switch used for switching a power circuit, similar to a relay except with higher current ratings.

Functions of the LED Pilot Lights 

Red LED Light - Indication when all 220v power is OFF  or ON during load shedding.  OFF - No House Power.  ON - Power available from the Grid.

Green LED Light - Indication that the contactor has switched and that house power is now available to use.

Functions of the LED Voltage and Amp Meters.

LED Volt Meter - Measures the voltage from the Grid

LED Amp Meter - Measures the amps drawn by equipment in the household.

Note:  During load shedding all lights, meters etc  is OFF.  Once the power returns the Red LED Pilot light will be on as well as both the LED volt and amp meters.  Green light will be OFF.  The current voltage will be displayed but no amps as the contactor has not been energized as the Multi Function Timer is counting down for the period set.  Once this period has expired the contactor will be energized and the Green LED light will be on.  The Amp meter will also provide a measurement of the current amps drawn.  Power will be available to use by the household.  The delay will prevent over voltage/under voltage and power fluctuations etc.  The period of time set for the timer is therefor important as to provide enough time for the power supply to "settle".  Many times before the power comes on and goes off again after a few seconds.  This might happen several times with high voltage fluctuations in the mix that can cause damage. 

Function and operation of circuit breakers

By definition a circuit breaker is an electrical safety device, a switch that automatically interrupts the current of an overloaded electric circuit, ground faults, or short circuits. Circuit breakers "trip", shut off, current flow after protective relays detect a fault. Unlike fuses that were used previously, circuit breakers are not usually damaged so they can be reset as opposed to being replaced. Circuit breakers are used in residential and in industrial applications.

Future extensions to be installed for this unit

• Fitting audible alarm buzzers to indicate when the voltage or amps runs to high,  Currently this is manually driven by observing the meters and then switch off the earth leakage breaker.  This will reset the timer and it will count down again for the set period.  We are currently looking at automating this function.
  
• Fitting a change over switch to switch between the generator and grid power supply. 

Here is a useful link if you want to learn more about Time Delay Relay Basics: Relay Circuit and Applications

There you have it in a nutshell. I am quite confident that this unit provide protection in 95% of bad incidents. The other 5% is the risk factor while sleeping and not being able to monitor the return voltage after load shedding at night.  I gladly take the 95% instead of  having no protection at all.  Thankfully the power supply in Mossel Bay is fairly stable but one never knows what could happen in the future.

I would like to thank my son for designing and building this unit. The only problem I have with the unit is that some of the younger generation cannot spell the word "Controller"!  See spelling on cabinet.  Yes and the necessary ECOC was obtained.  Now onto the next project to alleviate the effects caused by load shedding.  The next project has been lined up.  More on this in a future posting.

As loadshedding continues, amateur radio also bear the brunt.  Many radio amateurs are not geared to operate their stations during loadshedding periods.  Well it is not going to get better soon.  Thankfully the GRHub Net and other links/repeaters operate as usual.  The Internet connection for the GRHub Network has been stable and thus far the node and radio has operated above expectations.  The only real problem comes in when loadshedding moves to Stage 6.  The batteries does not charge fully between the shedding stages.  During such events the RF Link on 145.550 Mhz might now and again be switched off to give the batteries some breathing space to charge.  This seems to have worked very well.  Thus far our bulletin broadcasts and nets were not affected.  Well we once again had a great net gathering this past Sunday.  A big thank you to all those that participated in the "Lippeklap" Net. You make the Net!!

Loadshedding killed my Home Network Router? How to prevent this from happening to other equipment in future!

I was wondering when some of my electronic and home appliances will let out the magic smoke due to loadshedding etc.  Just the other day I posted the following images and audio clip on the Amateur Radio 101 Telegram Group. 

Note:  If the audio clips stop playing just refresh your browser and click on start.  Alternative download the audio files when the download window appears.

 

Well the magic smoke was let out and the router died just after the power returned after a period of loadshedding in Mossel Bay.  My XYL is the star witness who watched the smoke event.  The smell of the smoke is another story on which I cannot elaborate here.

  

My son and I are currently busy building a time delay switch which will in future hopefully prevent smoke coming out of electronic equipment after loadshedding.  Well "Murphy" decided that he will intervene before we could finish the time delay switch project.  Be as it may we are currently busy with the project and I will post the end result on the GRHub Network Blog.

Image:  Sneak preview of the test project under construction.  After testing we decided to re-build all the equipment in a larger box.  I did not like the look and build.  Will purchase a new box before final installation.  Test conducted were successful!  More on this in a future posting.

Finally:  Getting a time delay switch installed in or near your home's DB Board is not I bad idea unless you have a good insurance company or enough money to by new electronic or household items.  I my case I was just to late to prevent damage from occurring.  But there is a saying "Once bitten twice shy!"  Hopefully this would also get rid of "Murphy" in my house!!!

DIY TVI Filter by ISAK ZS2I SK

Well this goes back many years. Let me just explain.  The current bearer of the ZS2I call sign is Johan van Aarde.  He is the son of the late Isak van Aarde ZS2I SK.  Johan has taken over his late father's call sign.  The DIY TVI Filter originated from Isak.  I regularly visited Isak when he was still alive.  One day as per usual we were sitting in his shack and Isak tried to work a station with 100 watt but this station could barely hear Isak.  No problem,  Isak turned on "Die Stoof" (1.5K Linear Amplifier).  Well needless to say that the station heard Isak a 5/9 into Kleinbrak River.  We were having tea and the next minute his phone rang.  Isak answered and I was told afterward that it was his neighbor complaining that she cannot play her electric organ as it emits strange sounds and she does not know why.  Yep, it was Isak's turn to play the electric organ on behalf of the neighbor.  As a good neighbor would do Isak installed this TVI Filter on her TV and also fitted other filters that cured the neighbor's problems.  He gave me a copy of the TVI Filter.

I would like to share this filter with others that might experience TVI while operating their station.  Just be careful to install such filters today at your neighbors as you might be accused of various problems.  It is not like it was in the olden days!!  You have been warned!!

Amateur Radio HOTA Activation: NG Mother Church (Moedergemeente), George

This past Saturday , 7 January 2023  the NG Moedergemeente Church in George was activated from 09h00 as a Heritage On The Air site by Corne ZS1COR.  Site approved:  NG Moedergemeente Church, George. HB0047  Corne would like to thank all those who contacted the station and also who assisted him during the activation.   A special thanks also to the NG Moedergemeente Church for allowing amateur radio to activate this beautiful church and heritage site!! 

 History: 

The Moederkerk (Mother Church), is a place of worship of the Dutch Reformed Church in George. The church was built in 1842. The cornerstone for the church was laid on 14 April 1832. Slaves were used for some of the building work like the digging of the six-foot deep by five-foot wide foundations. Due to financial problems it took 12 years to complete the church and it was consecrated on 9 October 1842. Although a historical building, the church is still active and sermons are held every Sunday. 

More information and images on this beautiful church is available HERE. 

What is HOTA?

H.O.T.A (Heritage on the air) is an amateur radio group that strives to motivate radio amateurs to learn more about history, and to keep history alive by activating a multitude of historical sites by using SSB, AM, FM, CW and even with Heliographs. Radio amateurs have great fun going out in the field and visiting places and areas where once history was made. Even if you do not like history there is places that were visited that might be of interest to you. You can even combine your other hobbies with H.O.T.A. Now that you have a faint idea of H.O.T.A it is time to learn more about H.O.T.A and the fun radio amateurs have and can have in activating historical sites. If you want to learn more about H.O.T.A you can visit the Heritage on the Air website by clicking HERE.
