What is a AC Potentiometer ?
AC Potentiometer Definition
An AC potentiometer measures unknown voltage by balancing it with a known voltage, including both magnitude and phase.
Types of AC Potentiometers
Polar type
Coordinate type
Polar Type Potentiometer
Measures magnitude and phase angle using separate scales and components like a phase-shifting transformer.
Coordinate Type Potentiometer
Measures in-phase and quadrature components of the unknown voltage using two potentiometers in one circuit.
Applications
Measurement of self-inductance
Calibration of voltmeter
Calibration of Ammeter
Calibration of watt meter

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
