Protection and Numerical Relays

Numerical relays are based on the use of microprocessors. The first numerical relays were released in 1985.

A big difference between conventional electromechanical and static relays is how the relays are wired. Electromechanical and static relays have fixed wiring and the setting is manual. Numeric relays, on the other hand, are programmable relays where the characteristics and behavior can be programmed. Most numerical relays are also multifunctional.

Numerical Protection Relays for Reliable Power Systems

At VASI ELECTRA PRIVATE LIMITED, we provide Numerical Protection Relays, advanced microprocessor-based devices designed to detect abnormal electrical conditions and protect power systems by automatically isolating faults. These relays ensure safe, reliable, and efficient operation of your electrical network.

Key Features of Our Protection and Numerical Relays:

? Integrated Protection Functions
These relays combine multiple protection algorithms—such as overcurrent, differential, and distance protection—within a single unit, suitable for generators, transformers, motors, and transmission lines.

? Advanced Signal Processing
With digital signal processing, the relays perform precise analysis of electrical parameters, allowing rapid and reliable detection of short circuits, overloads, and ground faults.

? Flexible Configuration
Our relays are highly configurable, making them adaptable to a wide range of applications and varying power system requirements.

? Monitoring and Diagnostics
Built-in self-testing, detailed fault records, data logging, and disturbance recording enable comprehensive system monitoring and diagnostics.

? Automation and Integration
These relays support continuous monitoring, remote control, and real-time data transfer, enabling seamless integration into automated smart grids.

? Minimal Disruptions
Advanced logic ensures coordinated protection, minimizing downtime by isolating only the faulty sections of the network.

? Compliance with Global Safety Standards
Designed according to international protection standards, our relays safeguard both equipment and personnel with fast and reliable fault response.
