BOLA – An IoT based distribution transformer monitoring solution (DTMS)

Around 20% of distribution transformers fail every year in India, compared to 2 – 3% in developed countries.

WHY DO TRANSFORMERS FAIL?

Insulation
Failure

Fire or
Explosion

Moisture
Ingress

Over
Loading

Oil
Decay

Improper
Maintenance

Line
Surges

Improper
System

Can this be avoided?

The answer is YES; most of these can be avoided with proactive monitoring and maintenance. Then why are these failures not prevented?

current practice of manual monitoring involves…

Maintenance staff to consistently monitor

Manual recording of data

MAINTENANCE IS DONE AT THE SCHEDULED TIME

NO ANALYTICS FROM DATA

INFORMATION IS NOT RECORDER AND ACCESSIBLE

However

Every important parameter cannot be monitored

No transparency and accuracy in recording data

Maintenance not baseed on real time condition of transformer

Data doesn’t give insights on corrective action to be taken

Right data may not be available to right people

Introducing BOLA

BOLA, our IoT based low-cost Distribution Transformer Remote Monitoring and Diagnosis solution, it monitors the transformer’s vital parameters online from any location in real-time. It will diagnose & amp; send alerts/notifications which you will receive on a Laptop or Phone whenever there is any abnormality sensed in the transformer. This allows maintenance to be scheduled and corrective action to be taken before the failure actually happens. The risk of failure is reduced using alarm rules and detection of deviation from a reference value or threshold (e.g., oil and winding temperature).

How BOLA works

Bola, our IoT based Distribution Transformer Monitoring Solution (DTMS) works by collecting real-time data from the transformer with the help of sensors and sends it to the cloud via a sim card. It’s a condition-based transformer monitoring solution- Data supported maintenance as and when required.
