A Low Voltage (LV) Current Transformer is an electrical device used to measure and monitor current in low-voltage systems while providing electrical isolation between high-power circuits and measurement instruments.

Working Principle:
The LV current transformer operates on the principle of electromagnetic induction. The primary conductor carrying the current passes through or is wound around the magnetic core. This alternating current generates a magnetic flux in the core, inducing a proportional current in the secondary winding. The secondary current is then used for metering, monitoring, or protective relays, while safely isolating the measuring instruments from the high-current primary circuit.

Features:

• High measurement accuracy and linearity

• Stable performance and low phase error

• Compact and easy-to-install design

• Provides electrical isolation for safety

• Suitable for both metering and protection

Applications:
LV current transformers are widely used in low-voltage power distribution systems, industrial automation, energy management, overload detection, and

The TR-EVT11-10 type electronic voltage sensor adopts the principle of resistance voltage division, and the epoxy resin is vacuum cast.
