General Specifications
   Phase       
   Your choices are...         
   Three Phase       Three-phase power contains three simultaneous sinusoidal or other alternating voltage patterns, typically 120° out of phase with each other. Higher power efficiency and smoothness of operation is possible with three-phase operation. Three-phase power is most typically used for industrial or high power motors. 
   Single Phase       Standard commercial and residential power is single-phase, meaning one sinusoidal or other alternating voltage pattern. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Form Factor

   Phasing       The tester checks for the sequence of the phases. 
   Quality Factor       The test checks the Q-factor of the windings. The Q-factor is a measure of the ratio of the energy stored in the windings to the energy lost during a cycle of operation. 
   Return Loss       The tester measures the return loss of the transformer when connected to a transmission line.  The return loss measures the impedance mismatch between the transformer and the transmission line. 
   Saturation       The tester checks the value of the voltage that produces the saturation current. 
   Surge Stress       The tester checks the strength of the windings (especially for fine wire transformers) when a high voltage surge is applied. 
   Turn Ratio       The test checks the turn ratio of the primary to the secondary windings. 
   Wattage       The tester measures the input power needed to energize the transformer at no load. 
   Winding Polarity       The test checks for the polarity of the windings. 
   Other       Other unlisted, specialized, or proprietary test parameters. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
