Insulation resistance measurement Ri is an important area of measurement of high resistance. Insulation resistance should be checked before the device is released, however, occasional control Ri is recommended and later in operation, as the aging properties of the insulation material are generally weakened. This way we check that the installation is properly performed. During measurement, the entire installation must be disconnected from the mains, ie the main fuses must be switched off. To be able to say that a device or installation is in order, the Technical Regulations for performing power installations in buildings and other TP, or the HRN standard for particular devices or machines, are determined. Riz is measured by the insulation scale - eg by multimeters or mega mommers. Two groups of measurements are required:

a) measuring the isolation resistance Ri between the conductor and ground
b) measuring the isolation resistance Ri between the guides themselves
Both measurements need to be carried out because the test can satisfy the first test and does not meet the other, and only if both points are checked and if they comply with the technical regulations, the installation may be connected to the EES.
