Dary Electric recommends for you



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

Wide ratio measurement range, up to 5A/5A ~ 25000A/5A or 5A/1A ~ 5000A/1A. Uses near power frequency heterodyne power supply for testing, preventing on-site power frequency electromagnetic radiation and series interference. Adopts 320X240 high-resolution large-screen LCD display with user-friendly interface and operation design. Uses high-end DSP control technology and precise software algorithms to ensure accurate and reliable measurement data. Has intelligent judgment of external wiring status, prompting wiring errors, ratio errors, polarity errors, etc.

Directly issues 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. Uses aluminum alloy case for shock and pressure resistance, 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%, i.e.:

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



Current transformer ratio tester with brand-new design concepts and high-end control technology, for on-site verification of current transformers, completely abandoning traditional CT testing bulky equipment such as large current generators, high-grade standards, and large cables,

only needs current transformer ratio tester (without any additional equipment) to achieve fully automatic measurement of errors at various points of 0.2S and 0.5S class current transformers on-site, and the measurement results comply with national requirements for transformer verification regulations,

truly realizing a revolution in CT on-site measurement. Accurately measures the ratio error and phase error of current transformers. The instrument has a simple interface, is compact and lightweight, and the entire instrument weighs less than 20Kg.
