Why Relay Protection is Non-Negotiable
In power transmission and distribution, protection relays are the vital organs of your system. They instantly detect electrical faults—from short circuits to overcurrents—and swiftly isolate the affected equipment. This critical action prevents catastrophic damage, minimizes downtime, and ensures safety for personnel and surrounding infrastructure.
SHP supplies and integrates industry-leading hardware, such as the renowned Siemens SIPROTEC series, ensuring every component is designed for fast, precise fault detection and reliable operation under the most demanding conditions.
Our Comprehensive Relay Product Range
Overcurrent Protection
Detects currents exceeding a predetermined limit, typically protecting feeders, transformers, and distribution lines from faults and overloads.
Differential Protection
Offers high-speed protection for expensive assets like transformers, generators, and large motors by comparing currents entering and leaving a protected zone.
Motor & Generator Protection
Specialized relays that monitor thermal overload, unbalanced currents, and rotor lock-out, ensuring the longevity and efficient operation of rotating machinery.
Universal & Multi-Function Relays
Flexible, programmable relays capable of combining multiple protection functions (e.g., distance, overcurrent, earth fault) in a single compact unit for substation modernization.
