ISOMETER® iso165C… Insulation Monitoring Devices (IMD) for unearthed DC drive systems (IT systems) in electric vehicles

Open the catalog to page 1

Insulation Monitoring Devices (IMD) for unearthed DC drive systems (IT systems) in electric vehicles Product description The ISOMETER® monitors the insulation resistance between the active HV components of an electrical drive system (Un = DC 0 V…600 V) and the reference earth (chassis ground). The patented measurement technology is used to monitor the condition of the insulation on the DC side as well as on the AC motor side of the electrical drive system. The ISOMETER® is assembled with three connectors. To achieve internal galvanic separation, connector 1 is connected to low-voltage (LV)...

Function (continued) The initial measurement values after power up are: HV relays open 50,000 kΩ 0V Value in V Insulation resistance Voltage of HV1 Voltage of HV2 HV relays closed Value in kΩ Value in V Value in V The ISOMETER® generates a pulsed measuring voltage that is superimposed on the IT system by terminals T_31_E/KE (chassis). Because the connection between the terminals E/KE and the chassis ground (T_31) is continuously monitored, it is necessary to install two separated conductors from terminals T_31_E/KE to chassis ground. Standards – corresponding norms and regulations General...
