a ct is a current transformer
the primary is one turn
this can be a hole you pass a wire thru the laminations
the wire you pass thru the hole can be 300v 600volt or 13200Volt insulation
the core is bolted to the enclosure
clamp on ammeter Amprobe are portable multi class current Transformers with meters right on the side

What does CL of a current transformer signifies?
CL of a CT is its accuracy class.. it is an approximate measure of the CT's accuracy. e.g. The ratio (primary to secondary current) error of a Class 1 (CL:1.0) CT is 1% at rated current
How do you calculate multiplying factor in 3 phase kwh meter using ct ratio is 600VA 5 class 5.0?
The question is incomplete, because there are no mention about CT & PT ratios. 600VA 5 can not be CT ratio.
What is single inheritance in c plus plus?
Multiple inheritance occurs when a class is derived directly from two or more base classes. class b1 {}; class b2 {}; class d: public b1, public b2 {}; // multiple inheritance class
What are the difference between 0.2 and 0.2S class in metering CT?
The 0.2S class is more accurate in meter reading than the 0.2 class. The 0.2S class is now mandatory for all meter reading.
Give the structure of multiple inheritance?
Java does not support multiple inheritance. It is done with the help of interfaces in java. a class can implement n number of interfaces, thus showing multiple inheritance. but a class cannot extend multiple classes in java.
Where is 5P20 CT used and where is Class PS CT used?
5P20 CT give more accuracy than PS class CT. 5P20 cant be used in unit protection. Class PS CT is a protection class ct. It is used for differtial proction,distance (UNIT)proction.

What is a c200 current transformer?
This is a class of current transformers, and is a fairly low class. This has to do with what kind of burden can be placed on the secondary. A general rule is a C200 current transformer can supply ~200 volts at full ratio to its' secondary. If the burden (the CT resistance + cable resistance + relay or instrument resistance) times the maximum expected current is higher than 200 volts, the CT is likely to saturate. During multiple fault events, a CT may keep some magnetizing current causing CT saturation to be higher on a reclose event. Typically CT's are sized and their ratios are chosen to minimize saturation when feasible.

Whether Current Transformer of 0.2 S Accuracy class having high ratio used for 1 percent load condition?
if mark specification of CT mention 5P20 + 0.2,am used at site seconder metering with class 0.2.my question is, at secunder CT site must used auxiliary CT with class 0.2, or not used.tank your answer.

What class of crime is larceny in CT?
PETIT larcenyis a misdemeanor. GRAND larceny is a felony.
What is single inheritance in c plus plus?
Multiple inheritance occurs when a class is derived directly from two or more base classes. class b1 {}; class b2 {}; class d: public b1, public b2 {}; // multiple inheritance class
What is the Difference between multilevel and multiple inheritance?
Multiple Inheritance : we can inherit more than one class in the same class. Multi-Level Inheritance: where one class can inherit only one base class and the derived class can become base class of some other class.
