An important factor affecting the accuracy of an electromagnetic current transformer is its excitation current, and the main factor affecting the magnitude and waveform of the excitation current is the characteristics of the CT core material. In order to analyze the influence of the core material on...
current transformer 意思是：电流互感器 以下双语例句：1.Analysis and simulation on saturation characteristics of current transformer.电流互感器饱和特性分析与仿真。2.When the power supply transformer secondary open-circuit, the primary winding is still current flowing through the certain, this c...
Although the magnitude of inrush current is so high but it generally does not create any permanentfault in transformeras it exists for very small time. But stillinrush current in power transformeris a problem, because it interferes with the operation of circuits as they have been designed to ...
Measurements of transformer inrush current offer important data for power system operation and protection. Since inrush current is the result of a system transient, it is difficult to observe this phenomenon and analyze its effect instantaneously. This paper proposes a simple model to represent and ...

A current transformer for a metal-encapsulated, gas-insulated switching installation has current transformer cores (10) which are arranged in metal encapsulation (2) (which is designed to be essentially rotationally symmetrical) and surround an inner conductor (1) which carries high voltage. An earth...
Simulation and Experiment Research on the Effects of DC-Bias Current on the 500kV Power Transformer In the paper, the effects of DC-bias current on the 500kV power transformer with three-phase five-limb core structure are investigated by calculation and e... FH Wang,J Zhang,CY Gu,... -...
The CurrentTransformer library measures RMS current values in a 50/60Hz AC circuit using current transformers. Each read causes the analog-to-digital converter (ADC) to measure a single AC cycle. The data gathered is processed using the standard RMS calculation to give the result in amperes. Th...
Select and optimize your current and voltage transformer data to fit protection and metering applications – rely on the CTDim dimensioning tool by Siemens.
transformer test instruments are used to determine whether your CT is functioning properly and that the power stays within the right parameters. Because CTs play an essential role in accurate consumer billing, transformer testing equipment is necessary to ensure accuracy in revenue calculation for u...
