Buy & Import Flexible Rogowski Coil Instrumental Transformers from Tianjin Grewin Technology Co., Ltd. - Wholesale Supply

Tianjin Grewin Technology Co., Ltd. supplies a Flexible Rogowski Coil Instrumental Transformer that can be clamped onto live busbars without dismantling. The design is lightweight and flexible, allowing quick installation in tight spaces while avoiding exposure to open‑circuited secondary windings. Its construction prevents core saturation even under overload conditions, preserving linearity.

The instrument uses the Rogowski principle to deliver precise current measurements, with typical industry values such as a ±800 A range and a frequency response up to 150 kHz. Accuracy is commonly around 0.6 % and sensitivity near 0.12 V/A, matching the performance of this model. Standard dimensions include an inner bend radius of about 25 mm, outer diameter roughly 70 mm, and a weight near 0.45 kg, suitable for most clamp‑on applications.

Target users include power quality monitoring firms, smart‑meter manufacturers and energy sub‑metering projects that need distributed measurement. The transformer supports multiple sizes, making it adaptable to various cable cross‑sections. Buyers should obtain the supplier’s MOQ, lead‑time and shipping terms directly from Tianjin Grewin Technology, as these details are not published.

The device is generally specified for a range of ±800 A, which suits most medium‑voltage monitoring tasks. Confirm the exact range needed for your system with the supplier before purchase.

Sourcing Flexible Rogowski Coil Instrumental Transformers from Tianjin Grewin Technology Co., Ltd. - China Import Guide

Prior to ordering, verify the coil’s inner bend radius, outer dimensions and the range of cable sizes it can accommodate within your installation layout. Request the supplier’s test data for accuracy class, frequency response and insulation rating to ensure the device meets your project’s technical criteria. Also confirm that any regional safety or electromagnetic compatibility standards required for your market are satisfied by the supplied certifications.

Logistics planning should include agreeing on the preferred Incoterm, such as FOB or CIF, and establishing clear payment terms before the transaction is finalised. Given the supplier’s current lack of response activity, set up a dedicated communication channel and obtain a written lead‑time estimate for production and delivery. Clarify packaging specifications, including protective cushioning and crate dimensions, to prevent damage during transit.

When the product arrives, arrange an independent inspection focusing on dimensional tolerances, measurement accuracy and insulation resistance. Obtain copies of the original CE, IEC and RoHS certificates as well as any calibration records. Maintaining these documents supports future quality audits and provides a basis for warranty claims should the transformer’s performance deviate from the stated specifications.
