Multipurpose Power Quality Test System

1. BACKGROUND

Power quality testing provides critical information to evaluate how an entire electrical or electronic system behaves under a range of real-world power conditions. These tests ensure that the system can operate reliably, safely, and within performance specifications. This testing requires hardware capable of generating voltage transients with high dV/dt and injecting signals at high bandwidth, while maintaining the required power levels. The complete system requirements are outlined below.

2. SCOPE OF WORK

This requirement is for the purchase of the brand name or equivalent BOLAB Multipurpose Power Quality Test System. Power quality testing is performed to help define system standards and typically includes steady-state operating points, line-step transient voltage, over voltage surge, input impedance sweeps, ripple voltage spectrum, and inrush/surge current limiting. The BOLAB Multipurpose Power Quality Test System, or an equivalent system, shall have the capability to inject controlled, high-bandwidth signals—up to 200 kHz—and apply a wide range of voltage and current waveforms to the system.

3. OBJECTIVE

BOLAB Multipurpose Power Quality Test System or equivalent is a critical component required to perform high-power power quality testing of electrical systems for both aeronautics and space applications.
