In my last post, I share a diagram about making a series testing board but my last diagram about a series board is only for connectivity testing, shortage testing, or compressor terminals testing in this post you will learn how can you make a testing board, from which you can test the low resistance electrical appliances such as Electric heater, iron etc.
Series Testing Board For Low Resistance Appliances Testing
For making or wiring this type of testing board you will require the below electrical substances.
2 Pin socket or Electric outlet
One way switch
bulb socket/bulb holder
Incandescent light bulb
How to make a series testing board for low Resistance appliances testing
To make or wire the complete series board, first of all, connect the phase/line wire to the socket./ outlet terminals and then connect the one-way switch. After that connect a wire between the outlet 2nd terminal and the bulb socket 2nd terminal, same connect an electric wire between the switch 2nd terminal and the light bulb socket/holder 2nd terminal where we connected an electric wire between the socket and holder. In last connect the neutral wire to the 1st terminal of the light socket/holder as shown in the below diagram.
How to Test Electrical Low Resistance appliances Short Circuit By electrical testing board.
After making this type of electric wiring circuit or board we can test any electrical appliance’s internal and external short circuits, e.g example if you want to test an electric heater. We know very well that electric heaters have very low internal resistance.
So if we want to test the internal short circuit in an electric heater using this testing board, first of all, plug in the heater shoo-in outlet and the light bulb will glow up completely but it’s not glow completely, it will be glowing 90 to 95 % and when we switch on the bulb will glow up to 100 %. It means that the heater has no internal short circuit. If the switch is on or off, the light bulb does not show any changes in light glowing then it means that the electric heater has an internal short circuit and if the bulb is not glowing then it means that the electric heater has an internal or external open circuit.
This post is about making a series testing board and its complete diagram however I will guide you further about the working and uses of the series board in an electrical circuit.
