TPS Class CT refers to a type of "Thermal Protection System" used in aerospace, particularly in vehicles re-entering the Earth's atmosphere, like space shuttles or spacecraft. The "CT" typically indicates a specific category or type of material or design within the broader TPS framework, focusing on its thermal resistance and structural integrity during high-temperature conditions. These systems are crucial for protecting the spacecraft and its occupants from extreme heat generated during re-entry.
C800 CT is a type of current transformer that is commonly used for metering and protection applications. TPS class CT refers to a specific accuracy class for current transformers that comply with ANSI standards. The main difference between the two is the design and accuracy specifications, with TPS class CT typically having higher accuracy levels.
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.
I am aware that Class TPS current transformers have a Low Leakage Flux design
TPS Class CT is used for transient performance (TP). TPS class Current Transformer has Low Leakage Flux and there is no limit for remanent flux) further there are also TPX,TPY and TPZ class CTs 1. TPX- No Limit for remanent flux due to nil air gap in the core 2. TPY - remanent flux does not exceeded 10 % due to less air gap in the core 3. TPZ- Having practically null remanent flux because there is large air gap is provide in the Core Er. Anil Prajapati, Protection Engineer,Jaipur RVPNL
What is the ISO protection class for Windsor Locks CT
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
CT class, or Computed Tomography class, refers to a categorization system used to classify the quality and performance of CT scanners based on factors like image quality, radiation dose, and capabilities. The selection of a CT class typically involves evaluating the scanner's specifications, intended clinical applications, and the needs of the healthcare facility, often informed by industry standards and guidelines. The goal is to ensure that the chosen CT scanner meets the diagnostic requirements while optimizing patient safety and comfort.

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.

PETIT larcenyis a misdemeanor. GRAND larceny is a felony.
The question is incomplete, because there are no mention about CT & PT ratios. 600VA 5 can not be CT ratio.
