PSL Ultra Precise Calibrated CT Data Sheet

Product catalog summary

Specifications:
The Ultra-precise CT series offers a range of rated currents from 5 A to 300 A, with nominal output at 0.333 VRMS at rated current. The magnitude accuracy is typically ±0.05% and specified at ±0.1% for readings between 2.5% FS to 120% FS at 50/60 Hz. The angle accuracy is typically ±0.07° and specified at ±0.1° for readings between 10% FS to 100% FS at 50/60 Hz. The series is certified under ANSI C12.20 Class 0.2 and IEC 62053-22 Class 0.2S standards.

Performance Parameters:
The crest factor is 3.5, and the fundamental frequency ranges are 50, 60, and 400 Hz, with a bandwidth of 40 Hz to 3000 Hz. Harmonic measurements are calibrated up to the 50th harmonic at 50/60 Hz, adhering to IEC 61000-4-7, class I accuracy.

Safety and Isolation:
The product is UL recognized with file number E469208 and provides isolation up to 600V. The leads are 12 ft (3.6 m) long, 18 AWG shielded twisted pair, with black as negative and red as positive.

Certified Influence Quantities:
The CT series is certified for various influence quantities including load, power factor, voltage, ambient temperature, frequency, phase sequence, harmonics, subharmonics, AC and DC magnetic fields, RF fields, conducted RF, fast transient burst, and oscillatory impulse.

Selection Guide:
Users can choose their rated current and select the corresponding "PSL Part Nb" from the provided table.

PSL Ultra Precise Calibrated CT Data Sheet-1

Ultra-precise Calibrated CT SeriesShielded Split-core Calibrated CTs for use with your PQube 3 PSL Ultra-Precise calibrated shielded split-core Current Transformers (CT's) are specifically designed to meet demanding accuracy applications. Split-core CT's provide low voltage linear output, proportional to the measured current. They don't require to disconnect conductor lines (open circuits) for installation. The CT's are individually calibrated at PSL to exceed the accuracy requirements of standard: ANSI Cl 2.20 Class 0.2 revenue grade (Class 0.2S IEC62053-22) • Easy and safe installation, no need to disconnect the line conductor. The CT connects low voltage signals to your PQube®3 current channel terminals • Fully shielded double-insulated cable for noise immunity • Ultra-accurate - Certified to IEC 62053-22 Class 0.2 revenue grade accuracy, IEC 61000-4-7 Class I harmonic accuracy - and unlike most other instruments, this certification includes both your PQube®3 accuracy and your CT accuracy, combined! • Excellent frequency bandwidth, designed for harmonic measurements to 50th harmonic at 50/60 Hz • UL listed , every CT comes with its own calibration file and NIST-trace certificate • Rated currents 5A through 300A Ultra-precise CT series - Revision 3 Power Standards Lab. 980 Atlantic Ave, Alameda CA 94501, USA Tel ++1-510-522-4400 Fax ++1-510-522-4455 www.PowerStandards.com
