Sleet storms and 20-below-zero temperatures are produced the year round to test electric power-line switches in this giant refrigerator at the Westinghouse East Pittsburgh Works.
Here a parka-garbed workman prepares an oil circuit breaker, or powerline guardian, for a high-voltage test.

Man-Made Winter Gives Switch a Test
Westinghouse Cold Laboratory:
To make certain that electric power equipment will operate efficiently even in Arctic weather, engineers at the Westinghouse East Pittsburgh Works test it at 20 below zero in a room-sized refrigerator.
Though encrusted with ice, this power line control switch handles 100,000 volts with ease.
