Extensive selection of tariffs
• 7 tariffs each for effective energy (consumption, delivery and
without backstop)
• 7 tariffs each for reactive energy (inductive, capacitive and
without backstop)
• 7 tariffs for apparent energy

allows changes to be identified in good time, e.g. insulation
faults

• Prevention of neutral conductor carryover
• RCM threshold values can be optimized for each individual
case: Fixed, dynamic and stepped RCM threshold value
