Numerical Protection Relays

Explore cutting-edge numerical protection relays designed for unparalleled precision and reliability. Safeguard your systems with state-of-the-art technology.

Autoreclose and Check Synchronism

Devices that automatically attempt to close a circuit breaker after a fault is cleared and ensure synchronisation for a stable power supply.

Busbar Differential

Protection relays that monitor electrical busbars, quickly detecting and responding to abnormalities to prevent potential damage in the power distribution system.

Capacitor Bank Protection

Specialised relays designed to safeguard capacitor banks, ensuring their proper functioning and protection against faults or excessive stress.

Circuit Breaker Failure

Relays that swiftly detect and respond to circuit breaker failures, preventing disruptions and enhancing the overall reliability of the electrical network.

Distance Protection Relay

Utilises distance-based measurements to identify faults along power lines, triggering protective actions to maintain the integrity of the electrical system.

Dynamic Line Rating and Interconnection Protection

Relays that assess real-time conditions to dynamically adjust line ratings, optimising power transfer and protecting interconnection events.

Generation Protection

Relays dedicated to protecting power generation equipment, ensuring safe and efficient operation by promptly responding to anomalies and faults.

IEC 61850 Numerical Substation

Relays compliant with the IEC 61850 standard, facilitating communication and interoperability within digital substations for enhanced monitoring and control.

Line Differential and Phase Comparison

Relays that compare phase currents at both ends of a power line, rapidly detecting and isolating faults to prevent widespread disruptions.

Marine Protection

Specialised relays designed to protect electrical systems on marine vessels, ensuring reliable and safe operation in challenging maritime environments.

Motor Protection

Relays dedicated to safeguarding electric motors by detecting abnormalities such as overloads, faults, and unbalanced conditions, preventing motor damage.

Rail Protection

Relays tailored for railway electrification systems, ensuring the reliable and safe operation of electrical infrastructure in rail networks.

Transformer Protection and Control

Specialised relays for transformers, providing comprehensive protection against faults and abnormal conditions to maintain transformer health and longevity.

Voltage and Frequency Protection

Monitors voltage and frequency levels, triggering protective measures to maintain a stable power supply and prevent damage to connected equipment.
