Power Frequency PD-Free Test System with Oil-Immersed Test Transformer for Power Utilities Electrical Insulation Testing and Substation Maintenance
Product Description
5kVA/50kV Power Frequency PD-Free AC Withstand Test System
The 5kVA/50kV Power Frequency PD-Free AC Withstand Test System provides a controlled power-frequency high-voltage source for insulation withstand testing of electrical equipment. It is particularly suitable for power utilities and maintenance departments that need to verify insulation performance during equipment inspection, repair, and commissioning.
The system is composed of a Motorized Operation Console, Power Supply, PD-Free Test Transformer, and Voltage Divider. The motorized console is used to regulate the applied voltage, while the PD-free test transformer generates the required high-voltage AC output with a low partial discharge background. The voltage divider provides voltage measurement for the high-voltage circuit, creating a coordinated system for professional AC withstand testing.
