61500 Power Line Disturbance Simulation [VIDEO]

We’re going to be talking about how to simulate power line disturbances. Power line disturbances are defined as any variation in the AC voltage, whether it’s the amplitude of the voltage, a variation in the frequency, even the waveform itself. Power line disturbances also have other related terminologies such as Sag, Surge, Harmonic, Inner Harmonic, Transients, and Noise. Sag, Swell, Outages, Short Interrupts all relate...

62000H- S Solar Array Simulation [VIDEO]

I’m going be covering something referred to as solar array simulation, and it’s used when testing PV inverters without having to use an actual solar panel or solar array as the input power. We do it by incorporating into a DC power supply, a method of simulating an actual solar array. A typical or equivalent circuit is what you see in Figure 1. There are...

66205 DPM Harmonic Measurements [VIDEO]

Don’t miss a video! Subscribe to YouTube I’m going to be talking today about the Chroma 66205 Digital Power Meter and specifically, the ability for it to measure harmonics. Chroma designed this unit to meet the IEC 61000-4-7 standard, and that standard defines what the equipment capabilities must be when testing devices for IEC 61000-3-2. It’s a nice, small compact unit. It has four, big...

Automated Test Systems: Eight Questions to Help the Make or Buy Decision

Test managers today have a few options in expanding their ATE capabilities. They can scour through their ATE graveyard, roll their own in-house, or buy a commercial test system. The path should be chosen strategically as it is a decision that most companies have to live with for 5 or 10 years given the cost and the life cycle of modern ATE.  Often, however, companies...

Electronic Load for Low Voltage, High Current Applications

As server computers and networking systems become more powerful, point of load DC/DC voltages for CPUs are continuing trend lower (below 1V) while demanding higher currents. To satisfy the needs of test engineers, we have released a new DC electronic load for low voltage, high current applications. The 63206A-60-1000 DC Electronic Load provides up to 1,000A @ 0.6V (it derates linearly to lower voltages, e.g....
