Measurements of electric system parameters using combined measuring instruments When the phase sequence is correct, the display of the meter will show phase rotation to the right clockwise. The meter also measures the interphase voltage. If necessary, one must check the operation of the protection devices so as to make sure that they have been installed correctly and that their settings are correct.

The voltage drop value can be determined by measuring the circuit loop impedance or on the basis of a diagram given in Annex D to the HD standard. III Measurement reports Reports must be prepared from testing of new, extended, or modified installations, as well as from periodic inspections.

Acceptance reports must include details of the tested installation, to include the results of the visual inspection and the measurements. Any defects or shortcomings found during the inspection must be eliminated before the contractor declares that the installation meets the requirements of the PN-HD standard. If the acceptance report pertains to a modified or expanded installation, it can contain an instruction to repair or improve the installation.

The entries in the report must identify each circuit and its protective devices, as well as the results of tests and measurements.

An acceptance report must include the names of persons responsible for the safety, construction, and testing of the installation, taking into account the individual responsibility of those persons in relation to the person who ordered the work.

An acceptance report must include recommendations concerning the time interval between the acceptance inspection and the periodic inspection. Similar information must be provided in the periodic inspection report. Reports must be prepared and signed, or certified in other ways, by persons who are competent to perform the inspections.
