What is PM transformer?
What is PM transformer?
P.M. Transformers has manufactured medium voltage current and instrument transformers for protection and metering purposes since 1970. The transformers are manufactured to meet the physical and electrical specifications required by the customer and consulting engineers.
What is the difference between live front and dead front transformers?
Livefront terminations have high voltage connectors, arresters, or fuses are exposed to the operator after cabinet has been opened. Dead-front (separable insulated connector type): Often referred to as deadfront bushings. Safety is enhanced as there are no current-carrying parts exposed to the operator.
How many types of outdoor substation are there?

This system returns power to all valuable customers. This system also allows utility crews to delay any replacing or fixing the cable until with a more convenient time or when suitable equipment arrives at the faulted location. But all URD is not configured in a loop system.
What is the interface between overhead circuit system and Urd circuit system?
The interface between the overhead circuit system and the URD circuit system is the riser pole. At the riser pole, cable terminations provide the interface between the insulated cable and the bare overhead conductors or cable. Pothead terminations grade the insulation to prevent any kind of excessive electrical stress on the insulation.
