2.13.3.11 Technical specifications of the transformers

Basic reference conditions under which the transformers can be loaded with the rated
power P
● Continuous operation P
● Frequency 50 Hz to 60 Hz
● Degree of protection IP00
● Installation altitude up to 1000 m above sea level
● Rated ambient temperature t
Installation and operating conditions that deviate from these values, influence the
permissible continuous loads. For example, a lower ambient temperature of 30 °C enables
a higher utilization.
