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
