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.

Causes and Preventive Measures of Fire and Explosion in Oil Circuit Breakers
Causes of Fire and Explosion in Oil Circuit Breakers When the oil level in an oil circuit breaker is too low, the oil layer covering the contacts becomes too thin. Under the effect of the electric arc, the oil decomposes and releases flammable gases. These gases accumulate in the space beneath the top cover, mixing with air to form an explosive mixture, which can ignite or explode under high temperature. If the oil level inside the tank is too high, the released gases have limited space to expan
