Applications
-
Energy management systems (EMS) in factories, offices, commercial buildings
-
Current monitoring in power distribution panels and switchgear
-
Industrial automation for load estimation, fault detection and real-time analytics
-
Retrofit installations where minimal downtime is critical
-
Smart grid and renewable energy systems requiring accurate current sensing
Installation & Best Practices
-
Ensure main conductor is easy to access and the CT can clamp around it without disconnection.
-
Close the split core securely and install in panel or enclosure per local clearance rules.
-
Connect the secondary leads to your meter, EMS or relay system following manufacturer polarity recommendations.
-
Never leave the secondary side open-circuited when the primary is energized — always use proper burden or short the terminals.
-
Use shielded wiring or effective grounding practices in high-interference environments for best accuracy.
