Product Overview
The Goldhome HMYDJW-20kVA/100kV PD-Free AC Power Frequency Withstand Voltage Test Set is designed for power-frequency high-voltage insulation testing. The system combines an oil-immersed test transformer with a control console for regulating the test voltage and monitoring test conditions.
The equipment is intended for insulation strength and leakage testing of electrical equipment, electrical components, and insulating materials under high-voltage test conditions. The manufacturer's manual describes the test transformer series for use in power systems, industrial and mining enterprises, and research departments.
The system uses a single-phase transformer design. An adjustable voltage is supplied to the transformer's primary winding through the control equipment, and the transformer generates a corresponding high voltage at its secondary winding.
The actual test voltage, duration, connections, and acceptance criteria should be determined according to the test object and the applicable test procedure.

Main System Components
-
Oil-Immersed Test Transformer
The test transformer converts the adjustable low-voltage input into high voltage for the test procedure. The manual describes a single-frame iron-core structure, with the primary winding around the core and the high-voltage winding positioned outside it.
2.Automatic Control Console
The control console is used to set test parameters, control voltage adjustment, display operating status, and monitor the test process. The manual describes automatic and manual operating modes.
3Voltage and Current Monitoring
The system displays voltage, current, time, and status information. The manual also describes voltage and current measurement displays and protection functions for abnormal operating conditions.
4.Test Data Management
The data interface supports querying test records by start and end dates. The manual describes exporting the displayed test data to an Excel file.
