Three New Smart Distribution Products to Empower Modern Power Grids
As global energy systems evolve toward greater intelligence, resilience, and decentralization, Zhuhai Comking Electric Co., Ltd.—a trusted name in power distribution equipment—has unveiled three advanced solutions designed to meet the demands of modern smart grids: the CKPM502 Boundary Switch Control Device, the CSR010 Self-Powered Protection Device, and the CKTB100 Transformer Smart Terminal. These innovations reflect Comking’s commitment to delivering reliable, compact, and intelligent protection and monitoring technologies for utilities, industrial facilities, and renewable energy projects worldwide.
CKPM502: The Intelligent Guardian for Ring Main Units
As a leading boundary switch control device supplier China, Comking Electric has engineered the CKPM502 specifically for space-constrained environments like ring main units (RMUs) and compact switchgear. This device offers comprehensive protection—including phase overcurrent, zero-sequence overcurrent, under/overvoltage detection, auto-reclosing, and remote tripping—while supporting full “three-remote” functionality (telemetry, telecontrol, and telesignaling). With a sealed, maintenance-free design and a guaranteed operating time of ≤35ms at 1.5× setting, the CKPM502 ensures rapid fault isolation and enhanced grid reliability. It’s ideal for urban distribution networks, solar farms, and microgrid applications.
CSR010: Truly Self-Sufficient Protection Without External Power
For locations where auxiliary power is unavailable or unreliable, Comking Electric delivers a breakthrough as a self-powered protection device supplier: the CSR010. This innovative unit harvests energy directly from the primary current transformer, eliminating the need for external DC supplies. It provides robust overcurrent protection, zero-sequence detection, and direct-trip capability via external contacts—all while consuming less than 1W during normal operation and starting up with just 0.2VA. As an Overcurrent protection Self-powered protection device supplier, Comking enables cost-effective, maintenance-free protection for remote feeders, rural electrification projects, and compact substations.
CKTB100: AI-Enabled Smart Monitoring for 10kV Transformers
Positioning itself as a premier transformer smart terminal supplier China, Comking introduces the CKTB100—a next-generation terminal that transforms traditional transformers into intelligent IoT nodes. Built on a dual-core ARM+DSP platform with AD7606 high-precision analog-to-digital converters, the CKTB100 continuously monitors voltage, current, zero-sequence signals, switch status, ambient temperature/humidity, and busbar hotspots. Leveraging AI-driven thermal accumulation models and cloud connectivity, it enables real-time diagnostics, remote firmware updates, and predictive maintenance—turning passive assets into proactive participants in the digital grid ecosystem.
Comking Electric offers a complete portfolio for international markets, including: Microcomputer protection relays, Ring main units (RMUs) and switchgear, Dry-type and oil-immersed distribution transformers, Current & voltage transformers, EV chargers and energy storage systems, Digital substation platforms.
Founded in Zhuhai, China, Comking Electric has over 20 years of experience designing and manufacturing intelligent power equipment. The company is dedicated to advancing safe, efficient, and sustainable energy infrastructure through cutting-edge technology and customer-centric service.
