SAIFI
System Average Interruption Frequency Index
Formula
Total Customer Interruptions ÷ Total Customers Served
Example: If a utility with 500,000 customers records 1,200,000 interruption events in a year — SAIFI = 2.4 outages per customer per year.
CAIDI
Customer Average Interruption Duration Index
The third pillar — CAIDI tells you how fast crews restore power once an outage happens. It measures restoration speed independent of frequency.
CAIDI = SAIDI ÷ SAIFI — measured in minutes per event
What Do SAIDI & SAIFI Actually Mean?
Think of them as the grid's report card. Utilities, regulators, and engineers track these two numbers to measure how well a power network serves its customers.
SAIDI
System Average Interruption Duration Index
"How many total minutes per year does the average customer sit without power?"
Formula
Total Customer Outage Minutes ÷ Total Customers Served
Example: 72,000,000 outage-minutes across 500,000 customers — SAIDI = 144 minutes (~2.4 hrs) per customer per year.
SCADA Solutions for DISCOMs
We provide smart grid solutions covering system design, equipment supply, installation, control centers, communication networks, SCADA integration, commissioning of the entire system.
Traditional Grid
-
Faults discovered by complaints - Customers call the helpline. Only then does the utility know something went wrong — minutes or hours later.
-
Manual search in the field- Crews patrol entire feeder stretches physically to locate the fault. This takes hours and keeps more customers affected than necessary.
-
All-or-nothing switching - Isolating one faulty section means cutting power to the entire downstream feeder — affecting far more consumers than the fault itself.
-
No visibility, no control - The control room operates blind. Load conditions, network health, and switch status are largely unknown until someone checks physically.
DAS-Enabled Grid
-
Faults detected automatically - The system knows the moment a fault occurs — within seconds, before any customer even picks up the phone.
-
Instant digital location - The exact fault location is identified automatically from the control room. Field crews go directly to the right spot — no patrol needed.
-
Surgical isolation & fast restore - Only the faulted segment is isolated. Healthy sections are restored automatically, often within seconds, through alternate network paths.
-
Full real-time visibility - The control room sees the entire network live — every switch, every load, every alert — enabling proactive decisions, not just reactive ones.
How DAS Works
DAS operates across three interconnected layers — sense, communicate, and act — that work together seamlessly and automatically.

Solid Dielectric Automatic Recloser with RTU Integrated controller
Sectionalizer is a protective device which enables recloser to close successfully before it goes to lockout. The sectionalizer senses the fault current and count the number of attempts done by Auto recloser and get it operated to separate the faulty section of distribution line as per the set count and prevent the recloser to lockout itself.

Sense Always Watching
Intelligent monitoring points distributed across the network continuously measure power flow, detect anomalies, and capture every event the instant it occurs — day and night, across every stretch of the network.
Communicate Instantly Connected
A high-speed two-way communication backbone connects every monitoring point to the control centre — streaming live data in and transmitting automated commands out, with no human delay in the loop.
Act Smart & Automatic
The control intelligence analyses incoming data, identifies issues, and executes network switching decisions automatically — isolating problems, restoring supply, and optimising the grid without waiting for a human operator to respond.
Self-Healing Grid
The most powerful outcome of DAS — a grid that detects, isolates, and restores itself before most customers notice anything at all.
1 · Normal
Power flows uninterrupted. The system continuously monitors all zones in real time with no human intervention needed.
2 · Fault Detected
An event occurs on the network. DAS detects it automatically within milliseconds — before customers are aware of any problem.
3 · Automated Isolation
The network isolates only the affected segment. Switching happens automatically — surgically protecting healthy zones from the fault.
4 · Supply Restored
Power is restored to unaffected zones through alternate paths automatically. Field crews are dispatched only to the precise fault location.

Why India Needs DAS Now
India Grid — Active Transformation
Regulatory Position
DAS is now a regulatory and operational necessity — not an optional upgrade — for every DISCOM in India.
Surging Power Demand
Urbanisation, EV adoption, and industrial growth are placing unprecedented stress on distribution networks built for a different era. DAS provides the intelligence to handle dynamic, high-density demand without compromising reliability.
Renewable Energy Integration
With India targeting 500 GW of renewable capacity by 2030, power flows have become variable and bidirectional. DAS is the essential management layer that allows solar and wind to be safely absorbed into the distribution network.
RDSS Mandate
The Revamped Distribution Sector Scheme mandates feeder separation, real-time monitoring, and AT&C loss reduction across all state DISCOMs — with DAS as the foundational technology to deliver these outcomes and unlock RDSS funding.
Reliability & Commercial Pressure
Industries, hospitals, data centres, and smart-city infrastructure demand near-100% uptime. DISCOMs face financial penalties for poor reliability scores — making DAS a commercial imperative, not just a technical one.
