RDTL-501A Variable Frequency Transmission Line Parameter Tester: Precision on-site testing for HV lines with variable frequency and digital filtering for accurate measurements even in strong electric fields.
Description
The RDTL-501A is a sophisticated Variable Frequency Transmission Line Parameter Tester designed for on-site evaluation of power frequency characteristics in high-voltage transmission systems. Whether it's overhead lines, cables, or a combination of both, this device offers the precision needed for comprehensive analysis.
Integrated Design for Versatility, featuring a built-in variable frequency power module, the RDTL-501A Variable Frequency Transmission Line Parameter Tester is capable of adjusting the output frequency and voltage to match various testing requirements. This flexibility ensures that the instrument can adapt to different transmission line configurations.
Frequency Adjustment for Specific Needs, choose from multiple frequency settings: 47.5Hz/52.5Hz, 45.0Hz/55.0Hz, 57.5Hz/62.5Hz, and 55.0Hz/65.0Hz. This range allows technicians to simulate various operational conditions and accurately measure the response of the transmission lines.
Advanced Interference Mitigation, to ensure measurement accuracy in the presence of strong electric fields, the RDTL-501A employs digital filtering technology. This cutting-edge approach effectively reduces interference from power frequency electric fields, resulting in reliable data even in challenging environments.
Generator-Compatible for Emergency Testing, in situations where the main power supply is unavailable, the RDTL-501A can be operated using a generator. This feature is particularly useful for post-outage assessments, ensuring that power can be restored quickly and safely.
