Description
The GDHX-8300F is a multi-mode, high-precision wireless phase detector integrating local RF, GPS satellite timing, and base station three phasing methods, designed for safe, fast phase verification and synchronization on 220V–220kV AC overhead lines, substations, and long-distance grid interconnections. It supports contact/non-contact dual operation, with 130m line-of-sight RF for local use and GPS/BDS for 0.3–800km remote phasing, solving blind-zone and long-distance pain points.
The system includes two RF/GPS transmitters (X/Y) and one color LCD receiver, featuring 3.2″ true-color display (phase angle/frequency/vector/GPS status), human voice prompts (“in-phase/out-of-phase”), and IP63 dust/water resistance. Built-in rechargeable Li-ion batteries provide 12+ hrs runtime, while 4.2m telescopic insulated rods and CAT IV safety ensure live-line safety. Ideal for grid synchronization, loop closing, transformer commissioning, and cross-region interconnection.

Applications
Core Test Objects
· Overhead lines: 220V–220kV phase verification & synchronization
· Substations: loop closing, busbar phasing, breaker synchronization
· Long-distance grids: cross-region interconnection via GPS
· Transformers: commissioning, vector group check, primary/secondary phasing
· Cables: insulated cable phase identification (≤220kV)
· Blind zones: basement/substation shadow areas via base station
Typical Usage Scenarios
· Grid synchronization: before connecting two independent networks
· Loop closing: safe reconfiguration of ring-main systems
· Remote interconnection: 0.3–800km long-distance phasing
· Commissioning: new line/cable/transformer phase validation
· Fault diagnosis: phase mismatch, reverse phasing, or missing phase

FAQ
Q: What’s the max distance for GPS remote phasing?
A: 0.3–800km;works across cities/regions via satellite timing.
Q: Can it work in basements without GPS signal?
A: Yes. Use base station mode for blind-zone phasing.
Q: What’s the difference between GDHX-8300F and GDCR1600?
A: GDHX-8300F adds GPS remote + base station modes;GDCR1600 is local RF only.
Q: Does it support non-contact for 220kV bare lines?
A: Yes. Non-contact mode for >35kV bare wires;safe without direct contact.
Q: What’s included in the standard package?
A: Receiver, 2× RF/GPS transmitters, 2× telescopic insulated rods, Li-ion batteries, chargers, HV probes, ground cable, carry case, user manual, PC software.
