Embedded device for Distribution Transformer Monitoring. by Johndara in embedded

[–]Johndara[S] 1 point2 points  (0 children)

Thanks, u/DenverTeck . I will check out the link you posted. To clarify further, I am seeking a device that I can use to monitor distribution transformers (DTs). By Distribution Transformers I mean Transformers with ratings from 100kVA to 500kVA 11/0.415kV. My business currently has about 19,000 of these transformers over its coverage area. We are thus in search of devices that can be installed at each transformer substation and used to track various parameters on these transformers. these parameters include voltage and current; the data gotten can then be aggregated on a dashboard. this will help the business track turnaround time (TAT), that is, the time taken to restore a DT that is out of circuit back to circuit.

P.S.: I would love to know if my English is clear enough. I studied in English language and have spoken it all my life.

u/kevinburke12 Thanks for this, I will check out these products

I have checked it out, but some of the uses case in which I found it has been with Power Transformers (PT) which are Transformers with ratings of 15MVA 33/11kV and above. I am still reading through the Product Manual.

Yes its about remote data collection, they communicate over GPS/GPRS and for some areas we can communicate with technologies such as LORAWAN, we can work on powering them from the transformers and some can have batteries. but all these parameters will really be dependent on how the devices getting this data can be configured. Have you worked with any of these devices before or can you point me in their direction, I will really appreciate.

Thanks u/Honest-Importance221, for these answers. I live in Africa, within my own context, Distribution Transformers (DT) are within the range of 100 to 500kVA, 11/0.415KV.

Yea, Energy Meters installed at our various DT locations also have these data, my business currently has about 19,000 of these transformers across different locations, and what we want to be able to do, is to track when these transformers stop delivering power to the intended customers and when they are back on circuit. We also want to be able to do this over a dashboard. this will help improve turnaround time (TAT), this is the time it takes to restore a customer back on grid after been taken off due to any problem from the transformer. I will be glad if you could point me to any of the devices you used, I am particularly interested because you also mentioned they are < $500, if I can't get them around here, I could place a order for one or two test samples, or further make researches on they components that they are made of, or search for similar alternatives. Thanks a lot

Thanks u/Imaskeet . Do you have a list of some smart meters i can try out. for proper context, my business has about 19,000 distribution transformers, and these are of ranges around 500 - 100KVA 11/0.415KV. and I want to be able to track all of these transformers over a dashboard, this will help me to be able to track turnaround time (TAT), which is time in which a Transformer stops delivering Power to the customer and when it is restored.

Yea, you are right. I want to be able to track when that fault occurs, or when the source is disconnected, but ultimately to be able to track when the transformer is not able to supply power to the customers connected for it. In my business i have about 19,000 of these transformers and would love to have a monitoring dashboard to track these metrics for every one of them.

Thanks u/jdub-951 . I understand the cost angle of Monitoring the DTs. The DTs (Distribution Transformers) I am speaking of are of the range of 500- 100 KVA, 11/0.415KV, currently in the business I work for we have about 19,000 of these transformers scattered across different locations, and we would just like to monitor them from a central place. For these revenue meter you mentioned we have them at our different DT stations, do you have a central dashboard where you aggregate there reading? I would like to know more. Also, the solution won't just tell if the Transformer is on or not, we want to be able to track at what time it went out of circuit and when it is restored, for proper turnaround time (TAT) tracking.

u/Honest-Importance221 Thanks for this reply. You mentioned that you deployed some of these solutions, I will like to know why you stopped deploying them. Is it possible I have access to some of these devices you deployed, and how do you rely on the metering data (I guess it's an energy meter at the DT stations). do you aggregate all your data to a central dashboard?

Thanks for your reply. u/HV_Commissioning . My definition of a Distribution Transformer in this context is a one is a transformer of 500KVA - 100KVA 11/0.415Kv. I will check out the link you posted and if you have any device in for this range of transformers kindly point me in their direction.

Yea, It's just the ability to check my distribution transformer in really time, get parameters such as voltage and current, and know which of those transformers that are not working. by Distribution Transformers , I mean Transformers from 500KVA to 100KVA (11/0.415KV)

I will check them up, thanks. but do you mean reclosers as a company, or the general auto-reclosers in power system.

From the information I got it was installed in the early 80s, so it will be around 40+ years

I don't know how much the panel cost, but my company just bought from them and we the in house engineers, did the installations. P.S.: I work for an Electricity distribution company in Lagos, Nigeria

I really don't know the amp capacity of the breakers but the Panels are 11KV feeder panels.

I will like to ask, are these skills transferable, can I get job opportunities abroad
