IEC and IEEE Standard Portable Protection CT Calibrator¹

Product Description Product DescriptionIEC and IEEE Standard Portable Protection CT CalibratorModel 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.Main Free Application-CT/PT excitation and saturation test-Accuracy measurement of ratio and phase angle-Secondary loop burden measurement-Winding resistance measurement-Saturated and non-saturated inductance test-Transient CT parameters test-CT/PT polarity test-CT nameplate guess Main Features1) Able to test Protection CTs, Measuring CTs, TP class CTs and inductive PTs2) Test excitation characteristic and error curve based on low-frequency measurement principle3) Measure ratio, polarity, ratio error and phase displacement error based on voltage method4) Automatic demagnetization of the CT after test.5) Adopt patented multifunctional rotary mouse to replace the keypad6) Adopt 5.7 inches LCD screen for display7) Adopt DSP, ARM and embedded LINUX operation system8) Both local test and PC remote test available9) Higher measurement accuracy: 0.05 %10) Print test results directly by built-in thermal printer11) Small and light weight (9kg / 19.84 lbs) for easy transport Technical Principle Ratio error and phase angle error of CT tested by voltage measurement method Figure1 CT's equivalence principle diagramCT'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. Product ParametersTest StandardIEC61869-2(IEC60044-1,60044-6), IEC61869-3(IEC60044-2), IEEE/ANSI C57.13Maximum Knee Voltage Measurement40kVOutput Range - Voltage0~180V(RMS)Output Range - Current0~12A(RMS), 36A(peak value)Voltage Measurement Accuracy±0.05%CT Ratio Measurement - Range1~40000CT Ratio Measurement - Accuracy±0.05%PT Ratio Measurement - Range1~10000PT Ratio Measurement - Accuracy±0.05%Phase Measurement - Accuracy±2minPhase Measurement - Resolution0.01minSecondary Winding Resistance - Range0~300ΩSecondary Winding Resistance - Accuracy0.1%±1mΩBurden Measurement - Range0~300VABurden Measurement - Accuracy0.1%±0.1VAMemory Capacity>3000 groups test results○Power SupplyNominal Input VoltageCustomized (AC 220V/230V/120V/127V±10%, 1-Phase)Nominal Frequency50/60 HzRated Current10A At 230V / 12A At 115VConnectionStandard AC Socket (IEC 60320) ○Environmental ConditionsOperation Temperature0 ... +50 °C (+32 ... +122 °F)Storage Temperature-25 ... +70 °C (-13 ... +158 °F)Humidity RangeRelative Humidity 5 ... 95 %, Non-CondensingVibrationIEC 60068-2-6(20m/S2 At 10 ... 150 Hz) ○MiscellaneousWeight9kg / 19.84 LbsDimensions (W X H X D, Without Handle)340×300×150mm(13.39x11.81x5.91 In)Connection Port2 USB2.0 Ports, 1 Communication Port ○Safety Standards, Electromagnetic CompatibilityEMCThe Product Adheres To The Electromagnetic Compatibility (EMC) Directive 2004/108/EC(CE Conform)IEC 61326-1; IEC 61000-6-4; IEC 61000-3-2/3SafetyThe Product Adheres To The Low Voltage Directive 2006/95/EC(CE Conform).IEC 61010-1 Detailed Photos  Applications Company ProfileHAOMAI ELECTRIC POWER AUTOMATION is established in 1999 and located in Wuhan of China, which is specialized in developing and manufacturing electrical power test and measurement instruments.
