High Voltage Transformer 7500–9400Vac output (EC Custom Model 220034)
This open type transformer is used to generate a high voltage output in an air purification system.
Zig-Zag "Zero Sequence" Grounding Transformer Assembly, 600V, 20A/phase
Grounding (or Zig-Zag) Custom Transformer Model 215033 shown with cover removed on NEMA 1 enclosure. Also included is a 393 mohm 60A "neutral" inductor (smaller magnetic shown). The application is for the creation of a missing neutral connection from an ungrounded 3-phase Delta system to permit the grounding of that neutral to an earth reference point; also to reduce harmonic content. During a phase to ground fault the zig-zag transformer’s coils magnetic flux are no longer equal in the faulted line. This allows zero sequence current to now flow from the point of the fault to ground and return to the zig-zag transformer’s neutral.
34kVA Airport Lighting Transformer - Constant Current Regulator Application
This example custom power transformer is rated 34kVA @ 50Hz, 400Vin, 1620Vout. Input Impedance 5% Minimum, 20% & 60% Output Taps. Constructed of MW35&36C Rectangular Copper wire coils with dog-bone ventilation assembled onto a 26M19 Electrical Grade Steel core with Class H (180C) insulation. Used in a constant current regulator for airfield lighting power and control solutions.
