Equipment system for measuring the parameters of mains and power consumption Theseus Lab

Project title

Workstation for measuring the power consumption of electrical appliances.

Project execution time

Project start: 11/11/2014, Project completion date: 29/12/2015.

Customer

Belarusian State Institute for Standardization and Certification

PROJECT GOALS
AND OBJECTIVES

The workstation is designed for automated measurement of energy efficiency parameters of electrical and electronic equipment.

The equipment can be used in the following cases:

  • in measuring and certification laboratories and centers;
  • during the production, development and parameters monitoring of any electrical equipment.

The Belarusian State Institute of Standardization and Certification got the opportunity to measure the power consumption of electrical appliances and electrical installations.

PROJECT TECHNICAL
DESCRIPTION

The workstation consists of 6 power analyzers (single-phase and three-phase).

Operator connects the equipment under test to the power meters and reads the indication during the power consumption measurements. Measured values can be further used to assess the conformity of electrical equipment to the requirements of energy efficiency standards.
