Our multi ratio current transformers and protective current transformers offer flexibility for different power levels, making them ideal for dynamic renewable applications.

Key Applications of Wrapped Current Transformers in Renewable Energy Systems

1. Solar Power Plant Solutions

Solar farms demand accurate, real-time current sensing for energy balancing, grid synchronization, and fault detection. NJXSE’s low voltage current transformers and encapsulated current transformers are optimized for harsh outdoor and rooftop environments, featuring flame-retardant casings and excellent dielectric strength.

2. Wind Turbine Power Management

Wind turbines require robust and vibration-resistant current measurement devices. Our split core current transformers and open type current transformers facilitate easy maintenance and retrofitting, while the core balance current transformer provides zero-sequence protection for early fault detection in generator windings.

3. Battery Energy Storage and Microgrids

For peak shaving, load balancing, and battery health diagnostics, miniature and PCB mount current transformers are essential. NJXSE supplies compact, plug-and-play solutions for high-density microgrid cabinets and distributed energy storage modules.

4. Smart Grid and Digital Metering

Accurate billing and power quality monitoring rely on metering current transformers and DIN rail current transformers with verifiable accuracy and tamper-resistant features. NJXSE’s custom current transformer services allow seamless integration with existing meter systems, ensuring regulatory compliance and data integrity.
