Fourth Step. If U1 is greater than or equal to U2, a standard known resistance (Ro) is inserted between the negative side of the high voltage bus and the electrical chassis. With Ro installed, the voltage (U1') between the negative side of the high voltage bus and the electrical chassis is measured (see Figure 5). The electrical isolation (Ri) is calculated according to the following formula: Ri = Ro*Ub*(1/U1' – 1/U1) Figure 5 Measurement of U1’ Electrical Chassis Energy Conversion System Assembly REESS High Voltage Bus + + Energy Conversion System - U1’ R0 Traction System Electrical Chassis If U2 is greater than U1, insert a standard known resistance (Ro) between the positive side of the high voltage bus and the electrical chassis.
