Current sensors protect renewable energy power conversion
Current sensors for the renewable energy industry are used in continuous and reliable operation of wind turbines for major wind farm installations around the world. Its 1,000A-rated HCS 1000 Hall-effect sensors monitor the input and output power feeds of the main power inverter.
Its current sensors are directly linked to the main wind turbine control cabinet. The galvanically isolated, induced secondary measuring currents produced are proportionate to a primary system operating current. If they fall outside an allowed working range, e.g., sensing an over-current condition, the sensors can provide system shutdown protection to prevent operational failure.
System failure prevention and condition monitoring of electrical power conversion can be applied to other renewable energy applications of wave, tidal and solar power.
The company’s Current Sensors can be used with primary currents in the range of 100 to 3,600A and are available in both open and closed loop styles.
Key technical performance benefits are high immunity to interference, says the company, an extended operating temperature range and a more stable housing construction for harsh environment applications, with customer service and support. Customised solutions for low volume demands include optional I/O connectors and full EMC screened cable assemblies, depending on project requirements.
