GIC Frequency Monitoring Relays

GIC Frequency Monitoring Relays provide precise protection for electrical and industrial systems by detecting over-frequency and under-frequency deviations in AC supplies. They ensure stable operation of motors, generators, and sensitive equipment by triggering control outputs when supply frequency moves outside permissible limits.

🔧 Technical Highlights:

• Function: Monitors AC supply frequency and trips output when value exceeds or falls below the set threshold.
• Measurement Range: 45–65 Hz (nominal 50/60 Hz systems).
• Trip Settings: Independently adjustable upper and lower frequency limits.
• Trip Delay: Adjustable delay prevents nuisance tripping from transient fluctuations.
• Supply Voltage: Typically 24–240 V AC/DC (model dependent).
• Outputs: SPCO or DPCO relay contacts for alarm, shutdown, or load control.
• Indication: LED display for power, status, and trip condition.
• Mounting: Compact DIN rail 35 mm housing for control panels.
• Compliance: CE and RoHS; conforms to IEC/EN 60255 protection standards.

✅ Benefits:

• Protects motors, generators, and drives from damaging frequency deviations.
• Ensures stability of power supplies in grid-connected and generator systems.
• Adjustable thresholds enable tailored protection for different loads and networks.
• Compact and maintenance-free design for long service life.
• Universal supply compatibility for global application.

🚀 Applications:

• Generator and alternator protection systems.
• Industrial motor and drive monitoring panels.
• Renewable power and grid-interactive installations.
• Critical process and automation equipment.
• HVAC, lift, and building control systems requiring stable frequency supply.

GIC frequency monitoring relays provide reliable and adjustable frequency protection for AC systems, helping maintain operational stability and extend equipment life in demanding industrial environments.

FAQs

• Q: What does a frequency monitoring relay do?
  A: It continuously monitors the supply frequency and trips when it goes above or below the set limits, protecting connected equipment from instability or damage.
• Q: Can GIC frequency relays be used on both 50 Hz and 60 Hz systems?
  A: Yes. Most models are designed for universal use on both 50 Hz and 60 Hz supplies, with adjustable frequency thresholds to match application needs.
