Why Your Current Transformers May Be Holding You Back
- Excessive copper loss – Up to 15% more energy wasted due to uncontrolled impedance.
- Voltage regulation drift – Inconsistent output leads to product rejects and re‑work.
- Long lead times – Off‑the‑shelf units often require 6‑8 weeks, delaying production lines.
- Unclear compliance – Missing CE, RoHS, or ISO documentation can halt shipments.
- High purchase price – Low‑quality imports force you to spend 20‑30% more.
According to a 2025 industry survey, 42% of operations managers cite transformer impedance as the top cause of unexpected downtime.

Frequently Asked Questions
Q1: How is transformer impedance measured?
A: We use IEC 60076‑1 short‑circuit test at rated voltage, then calculate percent impedance (Z %) = (V_sc / V_rated) × 100%.
Q2: Can you customize impedance for a specific load profile?
A: Yes. Our R&D team can design windings, core geometry, and material selection to achieve any impedance between 1 % and 12 %.
Q3: What is the typical lead time for a 5 k‑unit order?
A: 5‑day mass production after design approval; 48‑hour prototype available for testing.
Q4: Which payment terms do you accept?
A: L/C at sight, T/T 30 % advance + 70 % before shipment, or PayPal for samples.
Q5: Do you provide after‑sales testing support?
A: We offer a 12‑month warranty, on‑site calibration assistance, and a free replacement for any impedance deviation > 2 %.
