Even Linear Loads Need Careful Consideration

Written on November 30, 2015 at 12:22 pm, by

The nature of the load that will be connected to the AC power source is very important in determining the correct type of supply. Generally loads can be classified as linear or non-linear. Linear loads consist exclusively of reactive, inductive or resistive components and can thus be modeled as an LCR network. Since the elements […]

Solar Array Simulation Enables Better PV Inverter Testing for Manufacturers As a result of improvements in solar array technology and government incentives for implementing green technologies, solar systems are becoming increasingly cost-effective for residential and commercial use. The onus is now on solar inverter manufacturers to keep up with the market’s rapidly accelerating requirements. The […]

Making Sense of MIL-STD-704 Testing

Written on November 13, 2015 at 7:58 am, by

To ensure that aircraft electronics and other electrically-powered equipment will operate reliably, you must test them under extreme power conditions. In the military world, MIL-STD-704 (now up to rev. F), “Aircraft Electric Power Characteristics,” establishes the requirements and characteristics of aircraft electric power. It deals strictly with power quality, and does not say anything about […]

Testing Electric Motor-Driven Equipment

Written on November 2, 2015 at 11:47 am, by

Many equipment and appliance manufacturers use California Instruments precision power sources to test products that use electric motors. These appliances and systems may include either AC or DC motors, sometimes combined with electronic controls. These motors power appliances such as vacuum cleaners and refrigerators, and commercial equipment, such as conveyors, elevators, and other industrial equipment. […]
