Product Features

Measurement and control highly intelligent

The measurement and control device adopts DSP technology, which can measure different types of parameters such as frequency, voltage, current, active power, reactive power, power factor, harmonic components, etc. It can also achieve automatic switching in unequal steps, and can realize harmonic limit exceeding, voltage limit exceeding, system oscillation alarm and protection functions.

Efficient, safe, and reliable

Adopting SVC series filtering compensation capacitors and HL series filtering reactors, the capacitors have built-in discharge resistors, and advanced processes such as dry technology, self-healing technology, and pressure-sensitive circuit breaker technology are adopted, which have long service life and strong overload capacity. The reactor has high linearity, small inductance error, small size, high temperature rating (H-level), and also has a complete temperature protection system and ventilation system.

Cutting technology

HKT non-contact fast surge free switching device or high-performance strong contactor for switching.
