GIS Partial Discharge Withstand Voltage Acceptance Test / GIS Withstand Voltage Test Equipment - Test Precautions? GIS Partial Discharge Withstand Voltage Acceptance Test / GIS Withstand Voltage Test Equipment - Test Precautions? The GIS withstand voltage test is a crucial step in verifying its insulation performance, and its operation requires meticulous attention. The following are the main precautions: I. Pre-Test Safety Confirmation 1. Complete Isolation: Ensure complete isolation of the GIS from all possible power sources. Connect grounding wires and set up safety barriers and warning signs. 2. Internal Cleanliness and Dryness: Confirm that the SF6...

AC High Voltage Test Apparatus/High Voltage Resonance Test System for GIS - Test Precautions?  The test precautions for the high voltage resonance test system are as follows: I. Precise Preparation Before the Test 1. Parameter Matching Calculation: Accurately estimate or measure the capacitance of the test sample and calculate the expected resonant frequency. Configure reactor combinations and taps reasonably according to the equipment's rated parameters (voltage, current, capacity) to ensure the system resonant point falls within the operating range. 2. System Inspection and Grounding: Thoroughly inspect the excitation transformer, reactors, voltage dividers, and high-voltage connection components...

Variable Frequency Series Resonance Test/Variable Frequency Resonance System - Test Precautions? The following are the test precautions for variable frequency resonant systems: I. Detailed Preparation Before the Test 1. Parameter Matching Calculation: Accurately estimate the capacitance of the test sample and calculate the resonant frequency range. Select appropriate reactor combinations based on the equipment's rated parameters to ensure the system resonant point falls within the effective operating frequency band of the frequency converter. 2. Comprehensive System Inspection: Check that the connections of components such as the frequency converter power supply, excitation transformer, reactors, and voltage dividers...
