Z-Brick®
The Z-Brick® is a piece of test equipment to quickly check the condition and abilty of a feeder to deliver power under loaded conditions.
The monitor introduces a momentary load that gives the ability to measure the impedance of the incoming lines. This offers a way to quantify the ablity for a feeder to deliver power. It can easly identify problems including undersized feeds or poor connections.

Accuracy |
Voltage= 0.5% reading +/- 0.3Vrms error. Current= 0.2% reading +/- 0.1 Arms error. Impedance = 1% reading +/- 0.030mΩ error TC = 0.001% / °C |
|
Measurement Details |
• Three phase or single phase measurements. • Load bank = 40 Ohm delta non-inductive. • Load estimate: 120v = 4.5Arms 208v / 3Phase = 9.1Arms 480v / 3Phase = 20.8Arms • Non-linear impedance sources (UPS or regulator) will cause incorrect readings. • Voltage flicker and high frequency noise can cause inaccurate results, recommended procedure is to take multiple readings. |
