Frequency 45 - 65hz Electric Meter Calibration Test Device With Smart Scanning Head
GF312D Three Phase Portable Electric Meter Calibration Test Device with Smart Scanning head
The instrument is a precision AC energy meter testing instrument, mainly used to test three phase energy meter error on site and measure all various of AC parameters.
Function and accuracy tests of measurement devices in electrical power systems are either prescribed by mandatory standards and regulations or form part of an established quality assurance concept. All types of measuring equipment, such as power quality measurement devices, electricity meters or transducers, can only provide valid measurement values after they have been properly calibrated.
Automated equipment for electricity meter testing. The accuracy of the power and energy reference meter is available up to 0.02 %. The reference meter measures all main and influencing quantities inclusive harmonic analysis and distortion of the test signals.
Our electric meter testing equipment can perform instrument transformer testing, revenue protection, and meter site testing. Depending on the specific task you want to accomplish, electric meter testing equipment will obtain the statistical data you and your customers need.
Application
The devices used to calibrate electricity meters must be routinely verified themselves. That’s the only way to protect consumers. Laborelec’s working standards are well suited to the task. We can carry out calibration on your site, minimising disruption to your calibration routine.
Laborary has a fully equipped calibration equipment with the most accurate energy standard. It can furnish an extensive accreditation portfolio that is recognised internationally.
