Why Your Operations Are Stuck with Inefficient Current Transformers

  • High purchase price – many suppliers charge 30‑40% above market average.
  • Low accuracy – class‑0.5 or worse leads to 5‑10% measurement error, affecting energy‑cost calculations.
  • Long lead times – 6‑8 weeks from order to delivery slows project rollout.
  • Compliance gaps – missing CE, RoHS, or IEC 61869‑2 certification triggers import delays.
  • Limited customization – one‑size‑fits‑all designs cannot meet specific burden voltage or frequency range needs.

Result: Over‑budget projects, delayed commissioning, and lost competitive edge.
