As the global energy landscape shifts towards digitalization and decentralization, smart grids and (AMIs) are undergoing unprecedented upgrades. Modern utilities and system integrators have long since moved beyond simple "data collection" for meters, demanding stringent challenges in "wide-area communication, remote control, and extreme stability."
Comparison of IEC and UL Standards for EV Charging Leakage Protection

Pulished on Apr. 10, 2026
Both the IEC and UL prioritize personal safety in EV charging leakage current protection. Still, their implementation paths differ: IEC focuses on the coordination of RCDs for both AC and DC components, requiring more detailed fault type detection; UL emphasizes closed-loop detection of the CCID, stressing the ability to interrupt fault current.

In the Turkish market, meter relays and current transformers (CTs) primarily comply with IEC standards and the local Turkish EPDK (Energy Market Regulation Authority) specifications. Due to Turkey's plan to replace 50 million smart meters by 2035, the market demand for components meeting high-performance standards is extremely high.
What is an RCMU and Why is it important for EV Charger?

Pulished on Feb. 09, 2026
In the electrical and industrial sectors, RCMU typically refers to a Residual Current Monitoring Unit. It is a critical safety component used to monitor for residual current ("leakage current") in a system in real time. An RCMU is a high-precision sensor or protection device primarily used to detect residual current in both AC and DC.
