Practically सिखे CT और AMMETER का Ratio अलग अलग होने पर क्या करना चाहिए @electrical Technician

How to Change Ammeter Scale as per CT Ratio

in This video You're going to learn something new Concept which is never told in your college/Company/Training center, I am Going to Share my Practical Work experience knowledge.

As we know while doing connection of ammeter and CT, their Ratio Must be same but if you don't have same ammeter and CT ratio, then you can Change the Ammeter Scale as per the CT Ratio to do the Connection.
To know how we can do, watch the video till End.

Q. What is an Ammeter
Ans - An ammeter is a measuring instrument used to measure the current in a circuit. Electric currents are measured in amperes, hence the name. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters.

What are the types of ammeter?
Type of Ammeter. ...
1-Moving coil Ammeter. ...
2-Moving magnet Ammeter. ...
3-Electrodynamic Ammeter. ...
4-Moving irom Ammeter. ...
5-Hot wire Ammeter. ...
6-Digital Ammeter. ...
7-Integrating Ammeter.

What does ammeter measure
an instrument for measuring either direct or alternating electric current, in amperes. An ammeter can measure a wide range of current values because at high values only a small portion of the current is directed through the meter mechanism; a shunt in parallel with the meter carries the major portion.

How to Use an Ammeter to Measure Current
Ammeters work to measure electrical current by measuring the current through a set of coils with a very low resistance and inductive reactance. This allows for a very low impedance, the force that opposes electric current, that lets the ammeter accurately measure the current in a circuit without interference or change due to the ammeter itself.
