Energy Storage
Examples:
– UPS
– Battery powered backup and standby systems
– Battery chargers
– Charging stations
– Battery management systems
– Energy storage systems
Important energy storage measurements:
– Capacity
– Runtime
– Cross over time
– Accumulated energy in/out
IntegraVision measures instantaneous positive and negative values of current flowing into and
out of the DUT. Data is captured at up to 5 M samples/second and values are integrated to
accumulate amp-hours and watt-hours. This high speed integration function makes it possible
to more accurately measure the power consumption of devices for which power usage and
power direction of flow fluctuates greatly. Thus, battery capacity can be calculated and battery
run-time can be determined based on real loading conditions as you observe current flow,
power flow, and energy increase/decrease in the storage devices.
For UPS and battery backup systems, thanks to IntegraVision’s single-shot measurement
capability, single events and cross-over time from AC line to battery backup can be captured
and analyzed.
Electrical and Electro-Mechanical Systems
Examples:
– Lighting
– Appliances
– Industrial machines
– Robotics
Important measurements for electrical/electro-mechanical systems:
– Instantaneous and peak power
– Power consumption
– Harmonics and THD
– Transients and dynamic current consumption
Testing of lighting devices often involves measurement voltage waveforms, current waveforms
and THD, because distortion in voltage and current waveforms is becoming more prevalent due
to the increasing complexity of control systems.
For appliances and industrial machines, you need to measure dynamic current and power over
individual actions (such as a cycle on a machine or a single motion of a robot). During actual
operating conditions, the time to accelerate/decelerate motors or to activate sub-systems can
range from several hundred milliseconds to several seconds. IntegraVision gives you insight
into power consumption and DUT behavior for short events (milliseconds) or over longer power
cycles (seconds, minutes, hours or even days).
