Transformer calibrator, transformer tester, transformer field tester, transformer on-site calibrator, automatic transformer calibrator, automatic current transformer calibrator, current transformer tester, transformer field calibrator, current transformer field calibrator, current transformer field tester
The measurement range of the ratio is wide, up to 5A/5A ~ 25000A/5A or 5A/1A ~ 5000A/1A. It uses a power supply with a frequency close to the power frequency for testing, preventing on-site power frequency electromagnetic radiation and series interference. It adopts a 320X240 high-resolution large-screen LCD display with a user-friendly interface and operation design. It uses high-end DSP control technology and precise software algorithms to ensure accurate and reliable measurement data. It has intelligent judgment of external wiring conditions, prompting wiring errors, ratio errors, polarity errors, etc.
Directly issue on-site verification conclusions, qualified or unqualified. The instrument can store and quickly print various measurement data, and all setting parameters can be saved after power-off. It uses an aluminum alloy chassis that is shockproof and pressure-resistant, ensuring the safety of on-site operators and equipment.
Measurement:
A. Ratio range: 5A/5A ~ 25000A/5A (5A/1A ~ 5000A/1A) Accuracy: 0.5%
B. CT error measurement range 5A/5A ~ 5000A/5A (5A/1A ~ 5000A/1A)
Current transformer measurement error: limit error meets 0.05%, that is:
5% rated current measurement error: ratio error 0.1 class, phase error 6′
20% rated current measurement error: ratio error 0.1 class, phase error
100%, 120% rated current measurement error: ratio error 0.05 class, phase error 2′
Load test: CT load 0.1Ω ~ 25Ω Measurement error: 1 class
Weight: 16Kg Dimensions: 420mm×370mm×320mm

The current transformer ratio tester uses a brand-new design concept and high-end control technology to verify current transformers on-site, completely abandoning the traditional CT testing bulky equipment such as large current boosters, high-level standards, and large cables.
Only the current transformer ratio tester (no additional equipment needed) is required to achieve fully automatic measurement of errors at various points of 0.2S and 0.5S class current transformers on-site. The measurement results comply with the requirements of national regulations on transformer verification,
truly realizing a revolution in on-site CT measurement. Accurately measure the ratio error and phase error of current transformers. The instrument has a simple interface, is small and lightweight, and the entire instrument weighs less than 20Kg.
