Veris Industries: Ensuring the Accuracy of Power Monitoring Sensors (1.89 MB)

Veris Industries, located in Portland Oregon, is a leading provider of energy and environmental sensors for commercial and industrial buildings. Their product portfolio includes a wide array of control system peripherals including air quality sensors, humidity sensors, leak detection systems, lighting control devices, network integration systems, power and energy monitors, pressure sensors, relays, temperature sensors, and more.

Veris products integrate with a facility’s main automation system, providing valuable feedback on energy consumption and helping building managers regulate and decrease a facility’s energy usage. The new Veris E3x family of Panelboard Monitoring Systems monitors power at the branch circuit level, making it particularly useful for facilities that use large amounts of power, such as data centers and strip malls. These facilities are often occupied by multiple tenants, and the E30 keeps track of exactly how much power is consumed by each.

Every E30 monitoring system is calibrated to a variety of ANSI and IEC standards, a task that requires extremely accurate electrical power standards. The E30 handles up to 120 amps and needs to be tested under signals that simulate real loads and a number of special waveforms that are specified by various building codes. Calibration requires a signal source that provides high accuracy phantom power (separate voltage and current) as well as degradations (frequency variation, harmonic distortion, interharmonics, fluctuating harmonics, flicker, and dips and swells). The high capacity of the E30 means that it requires higher levels of calibration current than any device previously built by the company.
