The previosly listed voltage variations affect refrigeration systems in 3 ways: Short-time blackouts make tha compressor run before the system’s pressures are equal. This increases the magnitude and duration of the starting voltage pick known as inrush. This produces a brief but very intense heating which progressively damages the compressor’s widing. The high operating tensions produce up to 80% more heat in a continuous and permanent way causing damages not only to the winding but also to the mechanical parts and lubricants. Finally, the operation tensions produce a similar effect when they are too low, and they can also make the motor try to start several times until the excesive heating activates the equipment’s thermal protection. For these reasons, we can assure our customers that the use of an electric protector can reduce up to 75% the indez of failures in compressors and electrical systems making equipment’s life longer.
