Distribution automation using distribution line carrier systems. Mains signalling requirements - Frequency bands and output levelsWhat is BS IEC 61334 3 1 Electrical equipment about? BS IEC 61334 3 1 applies to electrical equipment to be used in distribution line carrier (DLC) systems on both medium voltage (MV) and low voltage (LV) distribution networks. BS IEC 61334 3 1 specifies the requirements (frequency bands, output levels, spurious emissions, etc.) for MV and LV distribution networks respectively. BS IEC 61334 3 1 specifies disturbance limits in the frequency range from

• Train line type: voltage

Noise figure generalities

particular consideration for their proper compatibility

Additional or other measures are possible but require agreement between the interested parties

Oxygen free copper is a high ductility

standards and similar publications

The guidelines set out in this standard demonstrate how to do a risk assessment and identify all hazards – including machine design

It will enable them to quickly assess potential suppliers and to build contracts that are simpler and more focussed

Protection against corrosion and protection from damage by birds and rodents

but is not limited to:

does not permit any leakage during testing
