• Blown/Open fuse alarm• Over/Under voltage• Feeder/Phase overload• Unbalanced load• Energy direction (generation or consumption)
ALARM SETUP
LV ADVANCED SUPERVISION
• Earth Returning Current (ground faults)• Incomer measurements• Oscillography• Power quality monitoring according to
IEC61000-4: ✓Voltage harmonics distortions (THD)✓ Interrupts (duration, limits)✓Voltage dips✓ Flicker, Etc.
• Communication with software platform (reports)
LV RTU MAIN FUNCTIONS
Transformer supervisión / Power Quality / Oscillography
METER TRANSF/FEEDER/PHASE
• 100 % reliable
• 100 % supervised energy
• Single, 2 phase and 3 phase meter’s feeder
and phase detection
• Coupled/ringed feeder detection
• Energy balance per feeder
• Meter tampering detection
Smart meters mapping algorithm is executed to determine the electricalnetwork configuration and the customers served by each distributiontransformer, feeder and phase.

Comparisonto locate Smart
meters
ENERGY BALANCE → Clearly shows the power losses inthe LV distribution network and highlights potentialUNAUTHORISED electricity consumers
It provides the info to PLAN FORWARD and avoid energy supply problems
Enables the utility to BALANCE LOADS and reducepower losses
It helps to locate the failures on the grid faster, analyzingwhich and where smart meters are affected
SMART METERS MAPPING
The solution is HIGHLY COMPATIBLE with:
• Existing meters and concentrators
• Existing communication methods
• Existing vertical fuse switch solution based LV panels
Setup of customized ALARMS
PARALLEL OR RING FEEDERS → It detects parallel or
ring feeders, including connections of one phase from
several feeders
