Classification of Common Electrical Current Sensors
Current transducer is a kind of detection device that can sense the information of the measured current, and transform the detected information into the required electric signals or other forms of information output according to certain rules, so as to meet the requireme...Read more -
What is the Difference Between a Leakage Relay and a Leakage Circuit Breaker?
What are leakage relays and leakage circuit breakers? Regardless of slow or sudden changes in the current of the power supply line, when the leakage current reaches the rated action value and continues to exist, the leakage relay will trip. After the delay, if it is dete...Read more -
Introduction to Current-Sensing and Temperature-Sensing Electric Motor Protection Devices
The damage to the motor is mainly caused by the overheating of the winding resistance or the decrease in insulation performance, and the overheating of the winding is often caused by the excessive current flowing through the winding. There are mainly two types of electri...Read more -

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 -
