Restart again
Thread Content
Low voltage has restart functionality; does medium voltage have it?
For the control of medium and high pressures, it is necessary to introduce low-pressure control components, as well as various instruments and interlock safety devices for connection.
Self-starting equipment is installed as required by the production process, available for both high and low pressures.
The restart of high-voltage motors is equivalent to low-voltage protection, with a relatively long trip delay
Why isn’t a contactor used in the medium-voltage motor circuit?
Medium-voltage motors also use high-voltage vacuum contactors, but this is relatively rare
Medium-voltage motors are generally not started and stopped frequently, so using high-voltage circuit breakers is more cost-effective
The so-called restart of medium-voltage motors is achieved through a low voltage setting, with tripping occurring after a delay of 6–9 seconds
