Three Phase Solid State Relay (TSR) 90DA

The Three Phase Solid State Relay 90DA is an advanced solution for dynamic reactive power compensation in medium- and high-voltage networks. Equipped with fast thyristor-based switching, it provides seamless control of inductive reactive power, ensuring system stability, voltage regulation, and reduced harmonic distortions. Its compact yet robust design makes it ideal for demanding industrial applications, power plants, and utility grids requiring real-time compensation.

Engineered for efficiency and reliability, the TSR 90DA operates with minimal switching transients and reduced inrush currents, thanks to its controlled firing angle technology. The reactor is designed to withstand continuous operation under harsh grid conditions, offering high thermal stability, excellent insulation performance, and low total harmonic distortion (THD). It supports rapid switching operations, allowing instantaneous compensation without mechanical wear, thus increasing overall system life.

With a rated capacity of 90 kVAr, the Three Phase Solid State Relay 90DA is well-suited for integration into Static Var Compensators (SVCs) and FACTS systems, enhancing network flexibility. Its modular design simplifies installation and maintenance, while the digital control interface ensures accurate monitoring, fault diagnostics, and system protection. This makes the TSR 90DA a reliable choice for industries like steel, cement, refineries, and power transmission, where continuous and efficient reactive power management is critical.
