New energy sector
Provide new energy charging pile accessories and solutions to Turkey's leading power and electrical supplier.
The rapid growth of the new energy sector—including solar photovoltaic (PV) power, wind energy, electric vehicles (EVs), and energy storage systems—has created an urgent need for reliable, accurate, and efficient electrical measurement technologies. Among these, current transformer (CTs) and current sensors play a pivotal role in monitoring, controlling, and protecting power systems. By providing precise current measurement, they ensure operational safety, improve efficiency, and enable intelligent management of renewable energy resources.
1.1 Solar Photovoltaic (PV) Systems
In solar power generation, CTs and current sensor are used to measure the current output of solar panels, inverters, and distribution circuits. Monitoring real-time current flow allows operators to detect unbalanced loads, identify power losses, and track system performance. In large-scale solar farms, hundreds of sensors are deployed to monitor arrays and optimize energy yield. Additionally, current sensors enable maximum power point tracking (MPPT) in inverters, improving energy conversion efficiency.
1.2 Wind Energy Systems
Wind turbines operate under highly variable conditions, with fluctuating currents caused by changes in wind speed and load. Current transformers are essential in wind turbine generators to monitor output currents and protect against overcurrent conditions. Current sensors also provide feedback for pitch control, converter regulation, and fault detection. Accurate current measurement improves turbine efficiency, reduces downtime, and extends equipment lifespan.
1.3 Energy Storage Systems (ESS)
Batteries are the backbone of renewable energy integration, balancing intermittent generation with demand. Current sensors play a vital role in battery management systems (BMS). They provide precise measurement of charging and discharging currents, ensuring that batteries operate within safe limits. This helps prevent overheating, overcharging, or deep discharging, which could shorten battery life or cause safety hazards. CTs are also used in large-scale storage systems to measure grid connection currents and support load balancing.
1.4 Electric Vehicles and Charging Infrastructure
In the EV sector, current sensors are critical for traction inverters, on-board chargers, and charging stations. They measure current during acceleration, regenerative braking, and battery charging. Accurate current measurement ensures efficiency, protects components, and enhances driver safety. Charging stations also rely on CTs and sensors to monitor energy consumption, enable billing, and provide overcurrent protection.
1.5 Smart Grid Integration
The new energy sector depends on smart grids to integrate distributed generation sources. Current transformers are indispensable in smart grid substations, enabling precise metering, fault detection, and power quality monitoring. Current sensors embedded in smart meters and IoT devices allow utilities to gather real-time consumption and generation data. This enables load forecasting, demand response, and efficient energy distribution.
2.1 Overcurrent and Short Circuit Protection
Renewable energy systems are often exposed to fluctuations in current due to variable inputs such as sunlight and wind. CTs detect overcurrent conditions, allowing protective relays to trip circuits and prevent equipment damage or fire hazards.
2.2 Efficiency Optimization
In solar and wind systems, current sensors provide data that enables operators to optimize system efficiency. For example, they help in balancing loads, reducing transmission losses, and ensuring that inverters operate at peak performance.
2.3 Grid Stability and Power Quality
The integration of renewable energy into the grid introduces challenges such as harmonics, voltage fluctuations, and reactive power imbalances. Current transformers help utilities monitor grid conditions, identify anomalies, and maintain power quality. This ensures that renewable energy sources do not destabilize the grid.
2.4 Safety in Energy Storage and EVs
Batteries and EV systems require precise current monitoring to avoid hazardous situations like overheating or thermal runaway. Current sensors ensure that charging and discharging processes remain safe, extending the life of batteries and protecting users.
2.5 Data Collection and Smart Energy Management
The transition to digital and intelligent energy systems depends heavily on data. Current sensors and CTs provide real-time current measurement that feeds into energy management systems (EMS) and supervisory control and data acquisition (SCADA) platforms. This enables predictive maintenance, fault diagnosis, and better decision-making for operators.
As the new energy sector evolves, current transformers and sensors are also advancing:
Miniaturization and Integration: Smaller, smarter sensors will be embedded in devices for compact renewable systems.
High-Precision Digital CTs: These will enable more accurate real-time monitoring in smart grids.
Wideband Sensors: Capable of detecting fast transients, supporting next-generation inverters and converters.
IoT-Enabled Devices: Wireless CTs and sensors will provide cloud connectivity for advanced data analytics.
Current transformers and current sensors are indispensable in the new energy sector. They enable safe, reliable, and efficient operation of solar PV, wind turbines, energy storage systems, and electric vehicles, while also supporting smart grid integration. By solving challenges such as overcurrent protection, efficiency optimization, grid stability, and battery safety, they ensure the sustainability and reliability of renewable energy systems. As technology advances, these devices will become even more intelligent, precise, and connected, paving the way for a greener and smarter energy future.
