FRD Series Wired High-Voltage Phase Verification Device: Technical Specification
The FRD Series Wired High-Voltage Phase Verification Device is engineered to address the critical demands of phase verification, voltage detection, and ground fault identification in power systems. As a routine yet hazardous task in electrical operations, phase verification requires precision, reliability, and safety. Utilizing a metal film resistor voltage reduction principle, the FRD Series provides visual indication via analog meter pointers to distinguish between in-phase and out-of-phase conditions across voltage levels ranging from 3kV to 110kV, with an additional low-voltage variant for 380V applications. Its compact design, combined with robust functionality, makes it indispensable for field technicians.
Key Features
1.Dual-Mode Phase Indication: Audible alerts (voice prompts) and visual signals (LED indicators) activate during phase verification, ensuring unambiguous identification of in-phase (0kV indication) and out-of-phase (matching system voltage) conditions.
2.Pre-Operational Self-Test: Allows validation of device functionality using low-voltage inputs (220V/380V), ensuring readiness before high-voltage deployment.
3.Automatic Power Management: Integrated smart circuitry activates the device during use and powers it down during idle periods, optimizing energy efficiency and battery longevity.
Technical Specifications
The FRD Series offers six voltage-specific configurations, with performance parameters detailed below:
Rated Voltage (kV) | 3 | 6 | 10 | 35 | 66 | 110 |
Weight (kg) | 1.4 | 1.4 | 1.4 | 2.0 | 2.6 | 3.2 |
In-Phase Indication (kV) | 0 | 0 | 0 | <8 | <10 | <20 |
Out-of-Phase Indication (kV) | 3 | 6 | 10 | 35 | 66 | 110 |
Total Length (m) | 1.2 | 1.3 | 1.3 | 2.0 | 3.0 | 3.5 |
Insulation Rod Withstand Voltage (kV) | 10 | 30 | 42 | 105 | 200 | 330 |
Functional Advantages
1.High-Voltage Compatibility: Engineered for systems up to 110kV, with insulation rods meeting or exceeding IEC standards for dielectric strength (e.g., 330kV withstand voltage for 110kV models).
2.Ergonomic Design: Lightweight construction (1.4–3.2kg) and adjustable telescopic insulation rods enhance portability and operational flexibility.
3.Multi-Functional Utility: Beyond phase verification, the device supports live-line voltage detection and ground fault localization, reducing the need for additional tools.
Safety and Reliability
1.Insulation Integrity: Epoxy resin-coated insulation rods provide high mechanical strength and resistance to environmental degradation.
2.Fail-Safe Design: Non-contact measurement minimizes exposure to live components, while automatic power-off prevents accidental discharge.
Applications and Compatibility
The FRD Series is ideal for:
1.Phase synchronization during grid interconnection or transformer commissioning.
2.Routine maintenance of transmission lines, substations, and distribution networks.
3.Fault diagnosis in grounded or short-circuit scenarios.
The FRD Series combines precision measurement, operational safety, and user-centric design to streamline high-voltage phase verification tasks. Its adherence to rigorous technical standards ensures reliability in diverse electrical environments, making it a critical tool for power system technicians.
