Product Description
Product Details From Manufacturer
The Source Impedance consists of three inductors, one for each phase of a three-phase AC power network,
installed in a half-height EMS module. An additional resistor, of small resistance value, is connected in series
with each inductor to keep the reactance-resistance (X/R) ratio of the source impedance close to that of the
synchronous generator. The Source Impedance module is designed to limit the short-circuit current drawn from
the ac power source when response of protective relays is being tested.
Specifications
Impedance - 55Ω 82°
Nominal Phase Current - 1 A
Line-to-Line Voltage - 208 V
Cosmetic Notes
Signs of scuffing on outer frame from previous use, trace dust in crevices, cosmetic in nature, see pictures.
Testing and Functional Notes
This item is TESTED & WORKING, as pictured. See above for any additional notes.
