المميزات والفوائد
- Self-powered operation from CT secondary current eliminates separate auxiliary supply wiring, enabling cost-effective relay retrofit in legacy secondary substations with limited auxiliary voltage infrastructure.
- Mechanical target indicators identify which protection function operated after a trip without laptop or communications access, enabling rapid fault type diagnosis at remote Saudi secondary substations.
- Built-in secondary injection test sockets allow protection function verification without disconnecting CT wiring, reducing test time and eliminating the risk of open-circuiting CT secondaries during field testing.
- IEC standard inverse time curves (EI, VI, SI, LTI) selectable by front-panel switch satisfy all common overcurrent coordination requirements in Saudi Arabia's secondary distribution network without software parameterisation.
- Compact panel-mount format with standard 4U relay case fits existing relay panel cut-outs in IDT/CDT relay replacement projects without mechanical modification to the relay panel.
- Negative phase sequence (NPS) protection detects unbalanced loading and phase reversal conditions, protecting distribution transformers and induction motors from overheating caused by supply unbalance.
- Earth fault high-set (50N) instantaneous element provides fast clearance of ground faults on secondary distribution feeders, minimising fault damage at SEC secondary substations serving residential customers.
التطبيقات الصناعية
- SEC secondary substation electromechanical relay replacement programme, where ViP300 replaces aging CDT and IDT relays with self-powered digital protection without auxiliary supply infrastructure investment.
- ARAMCO Dhahran facility secondary distribution protection upgrade, where ViP300 self-powered feature eliminates auxiliary wiring work in crowded legacy switchgear cubicles during live substation upgrade campaigns.
- NWC water distribution pump station switchgear protection upgrade, where ViP300 provides motor and feeder overcurrent protection with built-in NPS for unbalanced 3-phase supply detection.
- MODON industrial estate tenant feeder protection at secondary distribution boards, where ViP300 provides cost-effective overcurrent and earth fault protection with minimal commissioning complexity.
- Saudi hospital and healthcare facility secondary distribution protection at site distribution substations, where ViP300 NPS detection protects sensitive medical equipment from supply phase imbalance.
- Commercial building basement substation feeder protection upgrade at Riyadh and Jeddah towers, where ViP300 replaces obsolete electromechanical relays with digital protection and mechanical fault indication.
- Telecom infrastructure site secondary distribution protection at STC and Zain base station substations, where self-powered ViP300 protects critical telecom supply without separate battery-backed auxiliary supply.
