What is Crystal Oscillator ?
Crystal Oscillator Definition
A crystal oscillator is defined as a device that uses the inverse piezoelectric effect to convert vibrations into stable oscillations.
Working Principle
The oscillator works by applying an alternating voltage to a crystal, causing it to vibrate at its natural frequency.
Circuit Design
Crystal oscillators are designed to operate in series-resonant mode (low impedance) or parallel-resonant mode (high impedance).
Frequency Stability
They offer excellent frequency stability, making them suitable for high-frequency applications.
Applications
Crystal oscillators are widely used in devices like communication systems, GPS, and microprocessors due to their reliability and low cost.

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
