These devices are integral to power management, energy optimization, and system protection. Understanding the differences between passive and active Power Line Transducers is essential for engineers... -
Acrel Unveils Comprehensive Medical IT System Solutions for Healthcare Electrical SafetyOverview Acrel Medical IT System aligns with two major international standard frameworks. For markets following IEC 60364-7-710—including Europe, China, Brazil, and Russia—the system employs Insulation Monitoring Devices (IMD) to continuously track insulation resistance to ground. For regions adhering to NFPA99 standards, such as the United States, Japan, and Canada, the solution monitors combined... -
Acrel LoRaWAN Energy IoT SolutionStandard and Policy In June 2025, the European Conference on Post and Telecommunications (CEPT) approved a resolution titled ECC DEC(25)02, explicitly permitting the sharing of low-power devices (LPD-S) with satellite communications (i.e., non-terrestrial cellular networks) in the 862-870 MHz short-range device (SRD) frequency band. This move... LoRaWAN, particularly its satellite-assisted deplo... -
How Do I Ensure Compatibility Of A Leakage Current Sensor With Existing Equipment?Ensuring the compatibility of a leakage current sensor with existing equipment is a critical consideration in modern electrical systems. With the growing emphasis on safety, energy efficiency, and system reliability, proper integration of a leakage current sensor can prevent potential electrical hazards while maintaining optimal performance of the connected infrastructure. Understanding Leakage Cu... -
What Is The Difference Between Split-Core Current Transformer And Rogowski Coil?In modern electrical systems, accurate current measurement is crucial for energy monitoring, protective relaying, and power quality analysis. Among the widely used current sensing devices, the split-core current transformer and the Rogowski coil stand out for their distinct characteristics, applications, and installation requirements. Understanding the differences between these two types of device...
