RMRT
Remote Insulation Resistance Measurement System
When measuring insulation resistance manually before motor startup, repeated circuit breaker withdrawals can cause contact gaps, leading to increased contact resistance and possible damage. In addition, there is a risk of electric shock due to human error. To prevent these issues, this system enables remote measurement of insulation resistance, fault prediction, and history management, thereby improving equipment reliability and preventing human accidents.
