Hiotron’s DTMS Solution

Hiotron Distribution Transformer Monitoring System aka DTMS redefining the capabilities and benefit to “Power Distribution Companies and Transformer manufacturers” that can be achieved by Monitoring Distributed Power Transformer Network.

DTMS Structure

Why IoT Based Remote Distribution Transformer Monitoring system?

In the era of rapid industrialization and fast changing industrial working environment, automation, big data analytics and internet of things playing a critical role. Planning downtime and physically monitoring various parameters of transformer, now seems to primitive age work for power distribution companies. Monitoring various common parameters from comfort of IT cell/ office become new norms.

Power & Distribution transformers are the main backbone for any power distribution network. Automation of distribution substations improves visibility of the low voltage (LV) network and helps a utility company to utilize the power network in an optimum way. Many utility companies around the world are implementing, or have plans to implement, a smart metering solution. The first step of distribution transformer system is monitoring distribution transformers and, due to the importance of this asset, monitoring of critical parameters is essential.

Hiotron’s  Distribution transformer monitoring system playing critical role in empowering distribution companies and transformer manufactures with handy and real time information about various common as well as advance level parameters which enable them to define life and performance of the unit. The compact DTMS solution along with high industrial grade sensor gives client the real-time and accurate info.

Frequently Asked Questions

DTMS isn’t just for protecting your transformer from failures. It also monitors parameters such as PF, Load unbalances, Overvoltage etc which showcase the quality of power and the losses associated with the usage of various equipment. By monitoring these and taking corrective action, one can save energy, plan their loading of different equipment and protect their equipment from failure. Further it helps in planning the maintenance of the transformer based on the condition of the transformer and helps outage. Hence, whether the transformer is new or old, it will benefit from DTMS.

Power Quality Audit (PQA) is just one time & manual process which can be performed only once periodically or when failure in terms of cost observed in the final billing wherein Remote DTMS is continuous & automatic real time remote monitoring device deployed right on the transformer. Hence, anytime variation or fluctuation in the load, apparent power, power unity due to failure of capacitor banks, harmonic filters or anything, it will be immediately notified to concerned authority to take corrective actions in-order to avoid extra energy billing cost.

Avg. Recurring cost INR500/Transformer/Month (MOQ1000 or above).

Hence, 6K/Year & 30k/5 Years. Hence, for each transformer if we are giving warranty for 5 years then recurring cost coming for remote & preventive maintenance approx. less than 10% of transformer cost (INR3.5Lacs).

Transformer Remote monitoring cannot replace Transformer Manual maintenance completely or compared with each other but with this OEMs or utilities can perform manual maintenance more effectively and in planned manner. This system will help them to shift them from time based maintenance to the condition based maintenance to reduce number of frequent site visits, streamline efforts in right direction and most importantly avoid firefighting, damage control scenarios by intimating to authorities before any failure happens using platform Predictive Maintenance tool.

Therefore, if we just compare maintenance expenses with traditional way versus maintenance expenses with DMTS solution then huge amounts of savings will be resulted as a payback of this complete solution.

Typically, on the support base of the transformer or within 1-2 meter of the transformer.

No, we don’t monitor the oil moisture as the cost of the sensor itself is very high and hence the cost of the solution will increase to a very high value which would not make sense to deploy on a distribution transformer.

Yes. This will require additional effort and cost

It will store the data and once network is restored; data will be sent back so no loss of data.

From the secondary output voltage of transformer (needs 230 V ac).

DTMS comes with IP 65 protection box.

Yes. Ideally it Takes around 1 hour to install the device.

No. We do it for distribution transformer with secondary output of 430v.

Default At every 15 minutes the data is collected and recorded in the dashboard with timestamp wherein it can be configured upto 1 minute.

Yes, all transformers are geo-tagged and shown on a single dashboard.

Mobile App is available only in Android.
