Performing a range of standard electrical tests on a regular basis has proven to be an effective way of gaining reliable insight into the operating condition of transformers. But, this has been a time- and cost-intensive job in the past. A true three phase test system can really make a difference.
Transformers are a critical and expensive equipment in the power system network. They function as a node to connect two different voltage levels. Hence, the availability of their service is vital in maintaining the continuous power supply to consumers. Since many decades, differential protection provides the best overall protection for a power transformer to protect against faults... - Narri Yadaiah, Nagireddy Ravi
