The HV Diagnostics TD30 is a portable, digital signal processor-based instrument designed for measuring the tan delta (dissipation factor) of electrical equipment. It’s particularly useful for evaluating the condition of medium-voltage (MV) and high-voltage (HV) cables.
The TD30 is designed to work with the HVA30, HVA30-7 and HVA34 VLF test systems making it suitable for testing 25kV and below cable systems. It features a 0-30kV tan delta bridge, real time display of actual output waveform, and configuration and data extraction through Bluetooth connection. It is also supplied with complete analysis software.
The TD30 is easy to use and requires very few connections. It is also rugged and durable, making it ideal for use in field environments.
The TD30 is used to measure the tan delta of electrical insulation. Tan delta is a measure of the loss tangent of an insulator, and is a good indicator of its overall health. A high tan delta value indicates that the insulation is degrading and may be at risk of failure.
Here’s a breakdown of its key features and functions:
- Tan Delta Measurement:Â Measures the dissipation factor, which is a reliable indicator of insulation degradation in cables.
- VLF Testing: Operates at very low frequencies (VLF) to accurately assess the dielectric properties of cables.
- Portability:Â Its compact design and lightweight construction make it suitable for field testing.
- Wireless Connectivity:Â Bluetooth technology allows for easy data transfer and remote control.
- High Voltage Testing: Can handle voltages up to 24 kVrms, making it suitable for various cable systems.
- Accurate Measurements:Â Provides precise tan delta measurements with high resolution and accuracy.
- User-Friendly Interface:Â Intuitive software and easy-to-use controls simplify operation.
- Cable Diagnostics: Assessing the insulation integrity of MV and HV cables to detect deterioration and potential faults.
- Preventive Maintenance: Performing regular tan delta measurements to track insulation condition and schedule maintenance proactively.
- Quality Control: Evaluating the quality of new cables before installation to ensure they meet required standards.
