Product Description
Product Description
CT PT Vt Analyzer for Substation Instrument Current and Voltage Transformer Testing
Model No.: CTP-200PDescriptions:
CT and PT Analyzer is the revolutionary testing system for various CTs and PTs according to standards IEC61869-2 (IEC60044-1,60044-6), IEC61869-3(IEC60044-2) and IEEE/ANSI C57.13.The Analyzer can automatically complete the test within seconds by one click of the patented multifunctional rotary mouse.It allows to test the knee-point voltage up to 40kV CTs and PTs on-site in power grids or in manufacturers' production facilities or test labs.
CT and PT Tester CTP-200 is only 9kg(9.84 lbs), which is easy to carry on testing site.

Technical Principle
Ratio error and phase angle error of CT tested by voltage measurement method
Figure1 CT's equivalence principle diagram
CT's equivalence principle is shown as figure1.
The main reason of causing ratio error and phase angle error is the error of excitation loss's current Iex and turns ratio Np/Ns. So for 5%, 20%,100%,120% rated current output, if Iex amplitude and phase position and true turns ratio Np/Ns are known, then the ratio error and angle error of CT at this time can be calculated. The tester calculates the ratio error and phase angle error of CT by the measured turns ratio Np/Ns and excitation loss Iex.
Turns Ratio Np/Ns can be got by inputting voltage on the secondary side under no-load condition and test the primary induced voltage. Iex can be got by test the secondary side's excitation characteristics. Because Iex is determined by the induced electromotive force of secondary circuit, Iex amplitude and phase angle can be got from excitation characteristics. When the secondary current and the secondary load are known, Vex value is also can be got by calculation and get Iex value by checking out the excitation characteristics data table.
CT and PT Tester CTP-200P was showed at THE 9TH INTERNATIONAL EXHIBITION ON ELECTRICAL TECHNOLOGY & EQUIPMENT in SECC, Ho Chi Minh City.
