Electrical safety measurements Current regulations require the measurements of electrical systems both during commissioning (after completing the installation, after any change or extension of the system), as well as regularly during the operation. The scope of acceptance or periodic inspection is specified in standard PN-HD 60364-6. Requirements for measuring instruments are defined in standard EN 61557. Protective measures include, depending on needs, the measurement of fault loop impedance, insulation resistance, continuity of protection and equipotential bonding, earthing resistance and...

The 3-wire method, used in all advanced instruments, allows user to eliminate the impact of surface leakage current. In case of cables, wrap the core insulation with metal foil, which is connected to the shield terminal of the meter - only leakage current flowing through the insulation is measured. The measurement by 3-wire method is recommended for large areas exposed to pollutants (cables of large diameter, HV bushings, transformers, HV switches): and to direct current Measurements on RCDs may be performed with MRP-201 meter or by multifunctional meters MPI-502, MPI- 505, MPI-508,...

Methods of performing measurements are described in detail at www.sonel.pl Earthing measurements may be carried out with multifunctional meters having the appropriate function and with specialist meters of MRU series. The method most commonly used for measuring earth resistance is the technical method, where the meter calculates the resistance by measuring the voltage across its terminals after applying test current. For measurements of individual earthing systems, the most commonly used is 3-pole method of potential drop, which enforces current flow in the following circuit: the meter -...

All devices comply with European directives on electromagnetic compatibility and safety and are marked with Family of AutolSO adapters facilitate the insulation measurements carried out with suitable devices on insulation of 3-, 4- and 5-wire cables, without the need of manual selection of pairs and combinations of the measured wires. Adapter cables ended with crocodile clips (depending on the position 3, 4 or all 5) are attached to the tested cable cores; when the measurement is started, the adapter connected with the meters, performs the sequence of all required tests. Earthing impedance...
