The XHTX206 transformer comprehensive characteristic tester is a new-generation revolutionary CT and PT testing instrument developed on the basis of traditional transformer VA characteristic, ratio and polarity testers that rely on voltage regulators, boosters and current boosters. Adopting a high-performance DSP and FPGA with advanced manufacturing technology, the instrument ensures stable and reliable performance, complete functions, high automation and high testing efficiency. It is a professional testing instrument for instrument transformers in the electric power industry.
Applications & Target Audience: Engineered for electric power utilities, metering departments, transformer manufacturers, and relay protection testing teams that perform on-site verification of current transformers (CT) and voltage transformers (PT).
Key Features
Complete functions: tests excitation (VA) characteristics, ratio, polarity, secondary winding resistance, secondary load, ratio error and phase error of CTs (protection, metering, TP class), as well as excitation, ratio, polarity, secondary resistance and ratio error of PT electromagnetic units.
On-site CT verification without standard CT, current booster, load box, voltage regulating control box or heavy high-current cables, greatly reducing workload and improving efficiency.
Accurate ratio and phase measurement: maximum permissible ratio error ±0.1%, maximum permissible phase error ±5min, enabling on-site testing of 0.2S class CTs with a CT ratio measurement range of 1 to 40000.
With the optional dedicated current booster, outputs 180A current for convenient on-site current flow testing.
Advanced frequency conversion method tests CT/PT VA characteristic curves and 10% error curves; outputs only up to 180V AC and 12Arms (36A peak), yet handles CTs with knee point up to 60kV.
Automatically outputs knee point voltage/current, 10% (5%) error curves, accurate limit factor (ALF), instrument security factor (FS), secondary time constant (Ts), remanence factor (Kr), saturation and unsaturated inductance.
Tests comply with GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207 and other instrument transformer standards, with automatic standard selection by transformer type and class.
One-key CT resistance, excitation, ratio and polarity test with the same wiring for all CT tests except load testing.
5.7-inch graphic transflective LCD, clearly visible in sunlight; rotary optical mouse operation; built-in printer for automatic test report printing; stores 1000 groups of test data without loss after power-off.
It is designed for electric power utilities, metering departments, transformer manufacturers, and relay protection testing teams that perform on-site verification of current transformers and voltage transformers.
Q2: What tests can it perform on CT and PT?
It tests excitation (VA) characteristics, ratio, polarity, secondary winding resistance, secondary load, ratio error and phase error of CTs (protection, metering, TP class), and excitation, ratio, polarity, secondary resistance and ratio error of PT electromagnetic units.
Q3: What accuracy does it offer?
It offers a maximum permissible ratio error of ±0.1%, maximum permissible phase error of ±5min, and voltage measurement accuracy of ±0.2%, enabling field testing of 0.2S class CTs with a CT ratio range of 1 to 40000.
Q4: How does it handle high knee-point CTs with low output?
Based on the frequency conversion method, it outputs only up to 180V AC and 12Arms (36A peak) yet handles CTs with knee point up to 60kV, automatically deriving knee point voltage, 10% (5%) error curve, ALF, FS and other parameters.
Q5: What makes it different from a conventional CT PT tester?
Unlike conventional testers that require standard CTs, current boosters, load boxes and regulator boxes, it completes CT resistance, excitation, ratio and polarity tests with one key and the same wiring, featuring a 5.7-inch sunlight-visible LCD, built-in printer and 1000-group data storage.
