High Voltage Inc TD-34E Tan Delta Bridge

Overview

The High Voltage Inc TD-34E Tan Delta bridge is a non-destructive diagnostic test device for evaluating the condition of shielded medium and high-voltage cable insulation. Operating at very low frequency (0.1Hz) with AC power, it measures the Tan Delta (dissipation factor/loss angle) to assess cable deterioration from contamination, damage, or water treeing. The device features wireless communication via XBee protocol to integrate with the VLF-34E test system and E-Link PC software for comprehensive cable diagnostics and report generation.

Key Features

• Wireless XBee protocol communication for integration with VLF-34E system
• Compatible with international cable testing standards (IEEE 400, IEEE 400.2, IEEE 433, DIN VDE 0276, CENELEC HD620 S1, NEETRAC CDFI)
• Non-destructive testing for accurate assessment of insulation condition
• Stepwise voltage increase capability to prevent cable failure
• PC software integration via E-Link for data acquisition and automated report generation
• Designed for use with very low frequency (0.1Hz) AC power sources

Applications

• Diagnostic testing of 5-25kV primary cables
• Assessment of cable insulation degradation in service
• Preventive maintenance programs for high-voltage cable systems
• Utility and industrial cable testing
