What is a Sensor ?
Sensor Definition
A sensor is a device that responds to changes in physical phenomena or environmental variables, converting them into readable signals.
Sensor Calibration
Sensors need calibration against a reference value for accurate measurements.
Active and Passive Sensors
Active sensors generate power within themselves, while passive sensors require an external power source.
Types of Sensors
Temperature
Pressure
Force
Speed
Light
Electrical Sensor
Sensors that detect and measure electrical properties, converting them into usable signals for analysis.

Classification of Equipment Defects for Relay Protection and Safety Automatic Devices in Substations
In daily operations, various equipment defects are inevitably encountered. Whether maintenance personnel, operation and maintenance staff, or specialized management personnel, all must understand the defect classification system and adopt appropriate measures according to different situations.According to Q/GDW 11024-2013 "Operation and Management Guide for Relay Protection and Safety Automatic Devices in Smart Substations," equipment defects are classified into three levels based on severity an

Application of Auto-Reclosing Residual Current Protective Devices in Lightning Protection for Communication Power Supplies
1. Power Interruption Problems Caused by RCD False Tripping During Lightning StrikesA typical communication power supply circuit is shown in Figure 1. A residual current device (RCD) is installed at the power supply input terminal. The RCD primarily provides protection against electrical equipment leakage currents to ensure personal safety, while surge protective devices (SPDs) are installed on power supply branches to protect against lightning intrusions. When lightning strikes occur, the senso

Reclosing Charge Time: Why Does Reclosing Require Charging? What Effects Does Charging Time Have?
1. Function and Significance of Reclosing ChargingReclosing is a protective measure in power systems. After faults such as short circuits or circuit overloads occur, the system isolates the faulty circuit and then restores normal operation through reclosing. The function of reclosing is to ensure continuous operation of the power system, improving its reliability and safety.Before performing reclosing, the circuit breaker must be charged. For high-voltage circuit breakers, the charging time is g
