Basic Knowledge of Electric Motor Protection Devices
Motor protection is to provide comprehensive protection for the motor, namely to give an alarm or protection when the motor encounters overload, phase loss, locked rotor, short circuit, overvoltage, undervoltage, leakage, unbalanced three-phase, overheat, bearing wear, a...Read more -
What is a Power Transducer?
Power transducers are instruments that can convert measured active power and reactive power into DC output. The DC current or voltage is linearly proportional to the input power and reflects the transmission direction of the measured power in the line. They are suitable ...Read more -
What Are the Types of Leakage Relays Based on Their Operating Principles?
Leakage relay is a protective device used to detect whether equipment has leakage and convert it into a switch signal. Generally, leakage relays are made into switches with certain breaking capacity and are self-contained. Commonly used leakage relays can be divided into...Read more -
Working Principle and Usage Precautions of Leakage Relay
Leakage relay is a device that detects line touch (leakage) current and sends a mechanical open/close signal to the control circuit. It can be combined with low-voltage circuit breakers or AC contactors of various specifications to form a residual current action protecto...Read more -
