A latching relay is a specialized electrically-actuated switch characterized by its two-position nature. Unlike conventional relays, it retains its contact position indefinitely even after power to the coil is removed. This memory function is achieved through distinct mechanisms, primarily mechanica

A latching relay, also referred to as a memory relay, bistable relay, or stay relay, distinguishes itself from conventional relays by its ability to maintain its state even after the signal that activated it ceases. Unlike traditional relays that necessitate continuous power to sustain their energiz

A current transformer (CT) is a crucial component in power systems, employed for accurately measuring high voltage currents while ensuring the safety of operators and equipment. Here's how it works and where it finds application: Structural Components:Iron Core: Made of low magnetic permeability mat
