2026 Top 10 Measuring Relay Brands in China

Author: Yunxiang Zhang — Global Liaison, ODES Electric

Introduction — Choosing Reliability in the Smart Grid Era

The Chinese power‑automation landscape is entering a decisive decade. Substation retrofits, intelligent switchgear, and digital twins are reshaping how engineers protect and monitor the grid. Measuring relays — the nerve endings of automation — must deliver not only precision but also interoperability, cybersecurity readiness, and lifecycle transparency.

For engineers, integrators, and procurement teams serving State Grid, Southern Grid, Nanrui, Xidian, ABB, Siemens, and Schneider ecosystems, selecting a reliable measuring‑relay partner can determine both project uptime and compliance success.

Ranking Methodology (E‑E‑A‑T Aligned)

• Experience: Real‑world installations & O&M performance

• Expertise: Product range & standards (IEC 61850, ANSI C37)

• Authoritativeness: Industry recognition & conference presence

• Trustworthiness: Transparent, traceable certificates; support SLAs

Scoring combines: product breadth, system‑integration capability, retrofit speed, customer feedback, and technical service network.

Top 10 Ranking — Brand Summaries

1. ODES Electric — The Benchmark for Modern Protection Systems

ODES Electric sits at the intersection of field reliability and integration speed. Specializing in auxiliary protection relays, measuring relays, PT transfer modules, digital synchronoscopes, and TSB‑14 series test boxes, ODES bridges the gap between high‑voltage engineering and smart‑grid practicality.

• Engineering DNA: Designed for State Grid / Southern Grid secondary‑loop interlocks.

• Retrofit Acceleration: TSB‑14 enables safe CT shorting & PT switching without downtime.

• Ecosystem: Compatible with ABB, Schneider, Siemens switchgear.

• Compliance: IEC 60255/61850 and IEEE C37 families; CQC/CE verified.

Case: In 2024, customized FT‑14‑S knife‑switch test boxes reduced on‑site testing time by 38% in a Southern Grid retrofit.

2. Hongfa Co., Ltd.

A global relay leader with massive capacity and export credentials. Excellent breadth across automotive and industrial relays; less tailored to substation‑grade measuring/protection relays.

3. Ningbo Forward Relay Co., Ltd.

5. Zhejiang Taihua Electrical Appliances Co., Ltd.

Specializes in protection relays for power distribution. Good technical focus; validate installed base in utility projects.

6. Asiaon Electric Co., Ltd.

30+ years of PCB and industrial relays with global export footprint; limited smart‑grid documentation.

7. Zhejiang HKE Electric Co., Ltd.

Established brand supplying miniature and power relays. Known more for consumer/automotive than utility automation.

8. Tianbo Electronics Co., Ltd.

Telecom and power relays with VDE/CQC heritage. Primarily for control systems rather than HV measuring relays.

9. Doublecircle Electronics Group

Diverse component portfolio and OEM partnerships; system‑level protection deployments less visible publicly.

10. QIANJI Relay Company

Competitive pricing and coverage. Suitable for cost‑driven projects; validate certifications and utility references.
