A ct is a step up transformer where as a pt is a step down transformer because both are used for measurement and protection purpose . current is stepped down if the secondary windings are more so we can obviously say thar ct is step up transformer

What electrical devices do you know?
Transformer Motors CT,PT Genrators these all are electrical devices
How do you calculate watt meter constant?
K=(voltmeter range*ammeter range*power factor)/wattmeter range
How electronic energy meter works?
By Using CT and PT, The RMS Current, RMS Voltage, True Power are measured by using Sample and Hold Circuits and converts into ADC then using Microcontroller or Microprocessor to calculate the Real values.
What is difference between high impedance busbar protection scheme and low impedance busbar protection scheme?
high impedance circit provides a varistor unit which has stabilising resistor which ll protect the relay from being operating for maloperations like through fault, CT faults whereas this varistor unit is provided internally in an numerical relay where the CT of class 5P can be used.
What is the difference between detector and diode detector?
difference between detector and diode
What difference value between K and Ct?
the same as the difference between ct and k
What is the difference between Ohms and Ohms CT in impedance of an audio transformer?
The difference in between Ohms and Ohms CT is that in Ohms CT it has CT at the end.
Multification factor of digital energy meter with ct and pt connection?
Multiplication factor can be derived from Meter CT, Meter PT, Connected CT and Connected PT values.
What Is The Difference CT and PT?
A CT is used to measure current, and is NOT referenced to ground, and has very low primary impedance. A PT is used to measure voltage, is referenced to ground, and has a much higher impedance (since it is referenced to ground).
What is the full form of CT PT transformer?
CT=========current transformer PT=========potential transformer these are the instrumental transformers.
Where did pt barnum live?
Either Bridgeport, Ct or Bethel, Ct
What is the time difference between IST and CT?
There is no time difference between Central European Time and Irish Summer Time.
What is the difference between 22ct gold and 14ct gold?
The difference between 22 ct gold and 14 ct gold is that 22ct gold is 91.6 percent gold. 14 ct gold has 58.3 percent gold. The higher the number, the more pure gold is.
What is the difference between a PT Cruiser touring edition and a PT Cruiser limited edition?
The difference between the PT Cruiser Touring Edition and the Limited Edition are related to the trim package. The Limited Edition has a different bumper, grill, and scalloping in the passenger compartment along with some extra electronics.
What difference value between Kt and Ct and K in gold?
Kt is American and Ct is English both mean the same thing.
Why can a CT be shorted and a Pt cannot?
A current transformer pushes a ratio of primary current in the secondary. A potential transformer pushes a ratio of primary voltage in the secondary. Shorting a CT allows the full current the CT wants to push to flow. Shorting a PT makes it very difficult for the PT to produce rated voltage. To keep the voltage at rated value, the PT would have to push ~infinite secondary current.
What is the time difference between Spokane US and London?
Spokane is located in the Pacific Time zone (PT). It is one hour behind Mountain Time (MT), two hours behind Central Time (CT), and three hours behind Eastern Time (ET).
