Energy & Utilities
Power generation, transmission, and distribution networks must withstand earth faults, switching surges, and changing load conditions without compromising grid reliability. Hilkar's equipment limits fault currents to safe levels, reduces short-circuit stress on switchgear, and maintains voltage stability from the generator neutral to the most remote medium-voltage bus. This helps power plants, substations, and utility networks remain operational during events that could otherwise result in service interruptions or outages.
Renewables
Wind farms and solar parks must perform as reliably as conventional power generating stations, despite variable weather conditions and frequent operation in weak grid environments. Hilkar's equipment helps maintain grid connection during faults, stabilizes voltage as renewable power output fluctuates, and mitigates harmonic distortion generated by power electronic converters. This enables renewable energy facilities to comply with stringent grid connection requirements and ensure reliable operation.
Data Centers
Data centers require uninterrupted power, yet modern IT equipment introduces harmonic distortion and significant reactive power demand. Facilities must test generators, backup power systems, and cooling infrastructure under full-load conditions before commissioning. Hilkar's equipment provides realistic load testing, mitigates harmonic distortion, and protects the electrical distribution system against ground faults. This ensures reliable power transfer and helps data centers achieve the high levels of availability and uptime they require.
Mining & Metals
Mining operations are often located at the end of weak distribution feeders, where draglines, hoists, and conveyors impose heavy cyclic loads on the electrical network. Hilkar's equipment safely dissipates regenerative braking energy, compensates for the reactive power demand of large motors, and maintains voltage stability to ensure reliable motor starting and operation without unnecessary upstream protection trips. Designed for harsh mining environments, our equipment delivers reliable performance despite dust, heat, vibration, and remote operating conditions.
Marine & Offshore
Ships, offshore platforms, and port facilities operate isolated power systems where salt-laden air, constant vibration, and limited space make conventional land-based equipment unsuitable. Hilkar's equipment protects onboard generators against ground faults, safely dissipates energy regenerated by variable-speed drives, and verifies system performance before commissioning. Every solution is engineered to resist corrosion and deliver reliable performance in the harshest marine environments.
Rail & Transit
During braking, trains regenerate electrical energy back into the traction power system. The traction network must manage this energy without compromising grid stability or affecting the public power network. Hilkar's equipment safely dissipates regenerative braking energy from locomotives and metro vehicles, supports the reliable operation of traction converters, and maintains the stability of feeder substations along high-speed rail lines and urban transit networks. Hilkar offers a comprehensive range of resistive and inductive railway equipment, engineered to railway standards for reliable, long-term operation in demanding traction applications.
Steel & Heavy Industry
Arc furnaces, rolling mills, and smelters impose large, rapidly changing electrical loads that can cause voltage flicker, harmonic distortion, and significant short-circuit stress at the grid connection. Hilkar's equipment mitigates these power quality challenges by providing reactive power compensation, harmonic filtering, and robust current-limiting solutions capable of withstanding severe thermal and mechanical stresses. This helps improve process stability, increase productivity, and ensure compliance with grid connection requirements.
