AC Dielectric Withstand Testing System Rated 150kV 10kVA for Pre-Commissioning and Acceptance Inspection of Transformers and High Voltage Electrical Equipment

Product Name: 10kVA/150kV Power Frequency PD-Free AC Withstand Test System

Before electrical equipment is accepted or put into service, insulation performance must be verified against the required AC withstand level. The 10kVA/150kV Power Frequency PD-Free AC Withstand Test System provides a dedicated high-voltage testing solution for acceptance, commissioning and insulation verification procedures.

The equipment is centered around a 150kV PD-Free Test Transformer and supported by a Motorized Operation Console, Power Supply and Voltage Divider. During a test, the operator can progressively apply the required power-frequency AC voltage and monitor the corresponding high-voltage level. The PD-free configuration is especially useful when minimizing test-source discharge is an important part of the testing environment.

• Acceptance-Test Ready: Suitable for insulation verification during equipment acceptance and commissioning procedures.
• Controlled Voltage Application: Supports progressive application of AC test voltage.
• PD-Free Configuration: Helps maintain low background discharge from the test source.
• Versatile Testing Platform: Can be applied to suitable transformers and other high-voltage electrical equipment.

• Pre-commissioning electrical tests
• Equipment acceptance inspection
• Transformer insulation verification
• Substation equipment testing
• Electrical installation commissioning
• Maintenance and service testing
