DC immune CT cores to a major client. Their positive feedback after thorough evaluation confirms the quality and effectiveness of our product. We are now engaged in active discussions concerning future orders.
DC immune current transformers (CTs) are crucial for energy metering, especially in applications with DC components in the AC current. These DC components can saturate traditional CT cores, leading to inaccurate measurements. Here's a breakdown of DC immune CT cores for energy meter companies:
Why DC Immunity is Important:
Accurate Energy Measurement: DC currents in AC systems, even small ones, can cause significant errors in traditional CTs. This is because the DC current shifts the magnetic operating point of the core, potentially driving it into saturation. Saturation drastically reduces the CT's accuracy, leading to under- or over-billing for energy consumption.
Modern Loads and Power Electronics: The increasing prevalence of power electronic devices like variable frequency drives (VFDs), solar inverters, and LED lighting introduces DC components into the grid. This makes DC immunity in CTs more critical than ever.
Regulatory Requirements: Some metering standards and regulations require or recommend DC immunity in CTs to ensure accurate and fair energy billing.
