How does insulation monitor work?
✅Insulation Monitors by DOLD: Insulation Monitoring Made Simple
DOLD's insulation monitors provide seamless insulation monitoring solutions. In the event of an insulation fault, the measuring circuit triggers, allowing a proportional small current to flow. The device's electronics evaluate this current, issuing a notification if the insulation resistance drops below a predefined threshold (response value).
What is an isolation monitor?
✅Explore the Importance of Isolation Monitoring in High-Voltage Vehicle Systems
Isolation monitoring stands as a pivotal safety feature in high-voltage vehicle systems. In modern vehicles, the high-voltage system remains completely isolated from the vehicle chassis. This design safeguards against electrical shock by preventing a single fault in the high-voltage system from posing a risk to individuals.
