True, I was looking for a good method to effectively get good grasp of the content of the standard and main points, these standards have lots of definitions and side details to the extend that one need to completely read a part of the standard to extract the main points.

May I ask you, why did you choose to go for a PLC instead of a microcontroller? All the functions you're seeking to support are radically available on microcontrollers, while for PLCs the supported languages of IEC61131-3 (LAD , grafcet, STL, SCL, CFC, etc..) would complicate the coding...

Problem statement: Following the occurrence of a short-circuit fault, high fault current flows in the power system. Unfortunately, this high fault current could damage the power system equipment causing high financial loss and extended power outages. Accordingly, the fault needs to be isolated...

Design a digital relay and a small radial DC/AC grid to test the relay on. The digital relay: A microcontroller with the digital protection algorithm code and a relay to trip the circuit. 1. Arduino Uno 2. Algorithm for digital relay protection, you can choose one of the following: sample and...

US has signed an agreement with the european countries to ban gas-fueled vehicles with a deadline of year 2035. So, I expect that from 2036 onward EV sales will skyrocket, unless a war or econimic crises forces the agreement to be delayed.

HaHa , good, but her transformer needs proper grounding safety first in electrical equipment :D

Test every bit of information you learn practically by buying the components and if this is not feasible due to price or availability constrains use a simulation software. This was a turning point for me, after I have started experimenting everything myself , even easy stuff, i got different...

There are numerous EV batteries testing standards: SAE J2380: vibration test (https://www.sae.org/standards/content/j2380_202112/) SAE J3277: Liquid leakage test https://www.sae.org/standards/content/j3277/1/ SAE J2288: Life cycle test (https://www.sae.org/standards/content/j2288_202011/) SAE...

Lead-Acid: Cheaper but shorter life , higher weight , and high toxicity Li-ion: longer life ,less weight , and low toxicity but the cost is higher So, go for Lithium-ion , if the cost difference is not a problem for you. Note that: - in some applications like drones ,electric vehicles...

Ideal batteries have constant voltage. This is not the case with practical batteries. In reality, the battery voltage is a function of the battery capacity. The shown curve is for lithium ion battery. The exponential region is from Vfull (4.2V) to Vexp (4.6V). In this region, the battery...

Can you elaborate more? What is your problem ? 1. How to display the data 2. How to do the calculation 3. where to buy the OLED Also, which microcontroller are you using ?

Late, but you could use the normally open and normally closed contacts of a relay NC: connect to the battery (So this is the default option for starting) NO: connect to the generator At the moment you want to toggle the supply , command the relay to toggle contacts.

You need to provide more info 1. PLC type 2. PLC manufacturer 3. Sequence of operation. 4. Type of DC motor control : speed control (analog) or just ON/OFF. Giving a guess, It seems like a sequential process with events. You could use state diagrams to design it. Create a finite state machine...
