What is insulation monitoring?
TI has both reference designs and devices designed to simplify the design process. Insulation monitoring, also known as insulation check, isolation monitoring, isolation check, ground fault detection or ground fault sensing, monitors the amount of insulation between high-voltage terminals and protective earth/chassis ground.
Why do we need a safety and insulation monitoring system?
The shift to higher voltages to minimize charging times – such as EVs trending from 400 V to 800 V and solar energy shifting toward higher voltage systems – increases the need for reliable safety and insulation monitoring methods.
Why do high-voltage systems need an IMD?
In a high-voltage system, electrical isolation is accomplished using non-conducting barriers such as insulation on cables, plastic housings on components, and physical distance. IMDs are needed to monitor these systems for failures, which could allow excess current to flow where it should not and pose an electrocution risk.
Why is high-voltage power important?
In electric vehicles, solar panels and energy storage systems, high-voltage power achieves faster charge times, minimizes power losses, and improves design reliability.
What is the withstand voltage test for Basic insulation?
According to International Electrotechnical Commission (IEC) 60950, the withstand voltage test for basic insulation is 2U + 1,000 VRMS, where U is the maximum operating voltage of a system. A manufacturer may need to apply a 4,242-V withstand voltage test when designing an 800-V system based on Equation 1:
Are high-voltage currents dangerous?
High-voltage currents have the potential to be dangerous or even deadly, however, so designers use insulation monitoring systems to send an alert or disconnect the power supply to prevent harm to the application or users.
How solid-state relays simplify insulation monitoring designs
Insulation monitoring detects insulation resistance by monitoring the leakage current from high-voltage terminals to protective earth/chassis ground. Since currents above 10 mA can be fatal,
