Withstand Voltage Tester AC Withstand Voltage Tester/Resonance Test Series -- Test Precautions? The general test precautions for the resonance test series (mainly including series resonance, parallel resonance, etc.) are as follows: I. Core Preparations Before Testing 1. Precise Parameter Matching: Key to Success. The capacitance of the test sample must be accurately estimated or measured, the resonant frequency calculated, and the reactor combination and taps rationally configured to ensure the system resonant point falls within the effective operating range of the device. 2. Comprehensive System Inspection: Check that the excitation transformer, reactor, voltage divider, and other...

AC Resonance Test System/Series Resonance Device - Test Precautions? The following are the test precautions for a series resonant device: I. Precise Preparation Before the Test 1. Parameter Matching Calculation: Accurately estimate or measure the capacitance of the test sample, calculate the resonant frequency accordingly, and rationally configure the reactor combination and taps to ensure that the system resonant point falls within the device's operating frequency range. This is a prerequisite for a successful test. 2. Comprehensive Inspection and Grounding: Check that the excitation transformer, reactors, voltage dividers, and other components are in good condition, and...

Partial Discharge-Free AC Resonant Test System/Partial Discharge-Free Series Resonant Test Device - Test Precautions? Test Precautions for Partial Discharge-Free Series Resonant Test Device: I. Precise Preparation Before the Test 1. Parameter Estimation and Matching: Accurately calculate the capacitance of the test sample, reasonably configure the reactor combination and taps, and ensure that the resonant frequency is within the allowable range of the device. This is the foundation for a successful test. 2. Check Grounding and Insulation: The casings and common grounding terminals of all components of the device (excitation transformer, reactor, voltage divider) must be reliably...
