Housing, Special Designs and Equipment

It transformers are installed in a housing this reduces heat dissipation. Either the power which can be drawn from the transformer is reduced or the maximum permissible ambient temperature. Heat dissipation through ventilation apertures or forced ventilation offers a remedy in this case. These measures are, however, directly linked to the required type of protection so that the conditions must be defined for each particular case. Means of electrical protection (fuse-link, circuit-breakers, etc.) and temperature monitoring are available for protecting transformers.
