FAQs of FRP Telescopic Earth - Discharge Rod (400 KV):

Q: How is the FRP Telescopic Earth Discharge Rod used during high-voltage equipment maintenance?

A: The rod is extended to the required length and securely connected to equipment using the universal clamp or croc clamp. The copper C hook is placed on the conductor to safely channel electrical discharge to ground, ensuring operator safety during maintenance or inspection.

Q: What are the primary benefits of using Fibreglass Reinforced Plastic (FRP) in this discharge rod?

A: FRP provides high dielectric strength (tested up to 400 kV) and mechanical resilience (>700 kg), while remaining lightweight and corrosion-resistant. This enhances safety for electrical personnel and longevity for regular field use.

Q: When should this discharge rod be operated in a substation?

A: The rod must be used before any maintenance or inspection on high-voltage equipment, as it ensures residual charges are safely discharged to ground, preventing accidental electric shocks.

Q: Where is this earth discharge rod typically applied?

A: It is primarily used in high voltage substations and electrical installations where the system voltage can reach up to 400 KV, serving as a critical safety device for operators and technicians.

Q: What compliance standards does the FRP Telescopic Earth Discharge Rod meet?

A: The discharge rod adheres to IS 2099, IS 2071, and IEC 60855 standards, validating its electrical and mechanical performance for demanding substation environments.

Q: How does the inbuilt discharge resistor enhance safety?

A: The integrated resistor (typically 20 M) controls the flow of current during discharge events, reducing the risk of arcing or sudden surges, thereby protecting users from electrical hazards.

Q: What is the typical process for inspecting or maintaining this rod?

A: Before each use, inspect for surface damage, ensure the insulation is intact, verify the mechanical integrity of the telescopic segments, and test copper hook connections for secure contact. Clean with recommended solvents and check markings for readability.
