WCT1-120AC-5A

WCT1-120AC-5A is used in a variety of industries and facilities. This device is designed to detect current, voltage, and phase sequence of alternating current circuits. It is most commonly used to signal an electric motor overload or to measure peak-excursion limits of running motor load current.This equipment is made of three main components: a bridge detector, a comparator, and a set of contact breakers. These components are connected in series and the bridge detector is responsible for measuring the current flow through the circuit. The comparator is then used to detect any undesired or dangerous levels of current. Finally, the contact breakers are triggered if the monitored current exceeds the predetermined current limit.Working PrincipleThe WCT1-120AC-5A utilizes the principle of inductance and capacitance in order to measure and detect current and voltage. Inductance is the property of an electrical circuit element to oppose changes in current and voltage in the circuit. Similarly, capacitance is the ability of an electrical component to store energy in an electric field.The bridge detector of the WCT1-120AC-5A utilizes a configuration of four resistors and one inductor, or "bridge", to measure the current passing through the circuit. The four resistors form a full bridge circuit, which ensures an accurate voltage measurement. The inductor acts as a current transformer, allowing the bridge detector to measure both current and voltage.Once the current and voltage measurements have been taken by the bridge detector, they are compared against predetermined limits by the comparator. If the current measurement exceeds the predetermined limit, the contact breakers are triggered and the circuit is shut down. This prevents the motor from overdrawing current and potentially causing a short circuit or other damages.In addition, the WCT1-120AC-5A also utilizes phase-to-phase sequence detection. This feature detects phase mismatches in three-phase power systems, and signals the switchgear accordingly. This feature helps to ensure the safe operation of a three-phase motor and its associated gearbox.ConclusionThe WCT1-120AC-5A is a versatile device used in a variety of industries and facilities. It utilizes the principles of inductance and capacitance in order to measure and detect current, voltage, and phase sequence of alternating current circuits. The device helps to ensure the safe operation of electrical motors and associated gearboxes by preventing overloading and preventing phase mismatches.
