Precision Voltage Measurement for Railway and Substation Applications – From 50V to 5000V with Adisens Hall Effect Sensors
Hall Effect Voltage Sensors for Railway Applications
Adisens Hall Effect Voltage Sensors are designed to meet the demanding needs of railway applications, where accurate, reliable, and safe voltage measurement is essential. These sensors are used for monitoring and controlling high voltages in railway electrification systems, ensuring the smooth and efficient operation of trains and infrastructure
Wide Voltage Range
Adisens Hall Effect voltage sensors can measure a wide range of voltages, from 50V to 5000V, making them suitable for various railway power systems, including overhead lines (catenary), traction substations, and onboard power systems.
Galvanic Isolation
These sensors provide high galvanic isolation between the primary high-voltage side and the low-voltage measurement circuit. This isolation is crucial for protecting sensitive control systems and ensuring operator safety in the event of electrical surges or faults.
High Accuracy and Precision:
Adisens Hall Effect sensors offer precise voltage measurement with excellent linearity and minimal error. This high accuracy is essential for ensuring stable power distribution across railway networks, preventing voltage fluctuations that could affect train performance.
Closed-Loop Technology:
The closed-loop Hall Effect design allows for fast response times and superior accuracy, even in dynamic railway environments where voltage levels can fluctuate rapidly due to varying loads or changing operational conditions.
Durability in Harsh Conditions:
Designed for harsh environmental conditions, these sensors are built to withstand extreme temperatures, vibration, and humidity, common in railway applications. This robustness ensures reliable performance in both outdoor and onboard environments.
Traction Power Supply Monitoring
The sensors are used to monitor and measure the voltage in railway electrification systems, such as overhead catenary systems (OCS) and third-rail systems. Accurate voltage measurement is crucial to maintain power supply stability and efficiency in traction networks.
Voltage Regulation and Control
These sensors provide real-time voltage data to control and protection systems, ensuring that the voltage supplied to trains remains within safe operating limits. This helps prevent damage to onboard equipment and ensures optimal train performance.
Substation Monitoring
In railway substations, Adisens voltage sensors monitor high-voltage lines, supporting transformer protection, load management, and power distribution. This ensures efficient power management and reduces the risk of power interruptions.
Onboard Power Systems
For onboard systems in trains, these sensors can monitor voltage levels in traction and auxiliary power systems, ensuring proper functioning of motors, HVAC, lighting, and other critical systems.
