SYSTEM PROTECTION

Safeguarding power infrastructure through reliable protection relay schemes, fault detection, and switchgear integration that minimize risk and ensure continuity of supply.

Relay Protection Switchgear Fault Detection SCADA Integration

OVERVIEW

PROTECTING EVERY KILOWATT IN THE GRID

System protection is the critical discipline that ensures a fault in one part of the network is isolated quickly and precisely, protecting equipment, personnel, and the stability of the wider grid. FABMIK designs, supplies, and commissions comprehensive protection schemes for transmission lines, distribution feeders, substations, and industrial power systems.

Our teams work with leading international protection relay manufacturers and bring deep knowledge of ANSI/IEEE and IEC protection standards. From simple overcurrent schemes on distribution feeders to complex differential, distance, and bus protection on 138 kV and 230 kV systems, FABMIK delivers protection solutions calibrated to your network’s specific characteristics.

We support clients through the full protection lifecycle: from system studies and relay coordination through hardware supply, panel fabrication, site installation, relay setting, and commissioning testing.

KEY ACTIVITIES

END-TO-END PROTECTION WORKS

Protection System Studies

Short-circuit analysis, relay coordination studies, and settings calculations to determine optimal protection parameters for your network configuration.

Relay Panel Fabrication

Design and fabrication of protection and control panels, marshalling kiosks, and metering panels to project specifications and applicable standards.

Site Installation

Field installation of protection relays, CTs, VTs, circuit breakers, switches, and all associated wiring within substation control buildings and outdoor switchyards.

Relay Setting & Programming

Application of calculated relay settings, logic programming, and scheme configuration using relay manufacturer software tools and tested against engineering study outputs.

Secondary Injection Testing

Functional testing of each protection element using secondary injection test sets to verify correct operation at calculated pickup and timing settings.

Commissioning & Handover

Integrated system testing, primary injection where required, operational sequence testing, and comprehensive as-built documentation for client handover.
