1. Why Current Transformers Fail Your Projects

You may be facing one or more of these costly issues:

High Purchase Price – Overseas suppliers quote 30‑40% above market average.
Low Accuracy & Poor Linearity – Leads to 5‑10% measurement error, risking non‑compliance with IEEE 1547.
Long Lead Times – 6‑8 weeks from order to delivery, delaying plant commissioning.
Inadequate Certification – Missing CE, UL, RoHS, or ISO‑9001 documentation creates customs headaches.
Limited Customization – Standard CT ratios (100/5, 200/5) may not match your protective relay settings.

Result: Production downtime, higher OPEX, and lost ROI.

6. Frequently Asked Questions

What are the main types of current transformer for industrial power monitoring?

The primary categories are bushing CT, wound CT, bar‑type CT, split‑core CT, and Rogowski coil. Each type serves different voltage levels, accuracy needs, and installation constraints.

Can you customize CT ratios and burden ratings?

Yes. Our R&D team can produce any standard ratio (e.g., 100/5, 200/5) or a bespoke ratio up to 10 000 : 5, with burden ratings from 0.5 VA to 15 VA.

What is the typical lead time for a 10 k‑unit order?

Standard models ship within 7‑10 days; customized orders are usually ready in 14‑21 days after design approval.

Low Power Transformer

Do you provide testing reports and certification documents?

All shipments include a full test report (accuracy, burden, insulation resistance) and the requested certificates (CE, UL, RoHS, IEC‑61869).

What payment terms are accepted for US buyers?

We accept T/T (30 % advance, 70 % before shipment), L/C at sight, and PayPal for sample orders.
