I2R Losses
LV Loss Zones• Transformer Connections• ACB Connections• Feeder Pillar Connections• Distribution Box connections• Meter Connections• LV ABC Connections• D Loops / Binding wire
Service Connections
LVDS carries High Currents
Each Connection generates a heat loss
Every Connection
counts
Equipment ~Loss Per Annum With Conventional/ Existing Connection System
Loss / p.a. for 1000 Nos. population
Transformer 11kV/415 V( 1 MVA)
INR 55000 INR 5.50 Crs
ACB 2000A INR 13000 INR 1.3 CrsPG Clamp Dog to Dog INR 2000 INR 0.20 CrsTotal Annual Loss INR 7 Crs
Conventional connectors have high I Square R Losses
1 Unit = INR 5/-
Excludes Cost of equipment failure and revenue loss

Faulty Meters
Tampered Meters
CT / PT Errors
No DT Metering
No Energy Audits
Theft
Bare Conductors / LV ABC / Service cables
Transformers/ Distribution Boxes / FP / Meters
Billing Errors
Incorrect Billing
Defaulters unpunished
Effects
Causes
Theft of Electricity
• Direct Hooking on Bare OH / Transformers / Distribution Boxes• Nails/ Insulation Piercing Connectors on LV ABC / Service Cables• Energy Meter Bye Pass
