Power & Energy
Calibration Consulting offers three solutions for calibrating power and energy meters, supplemented with the necessary supporting equipment.
Firstly, we have Meatest’s power & energy calibration systems: the M133C series in both single-phase and three-phase versions. This is the most cost-effective way to get excellent performance from a single instrument. If the specifications of the M133C are not sufficient for you, we also have two solutions from Measurements International (MI). These are the MI2100A and MI2100B models. The MI2100A has a base specification of 20 ppm with a maximum current of 5 A. For the MI2100B, this is a base specification of 30 ppm but with a maximum current of 100 A. For the M133C, these specifications are significantly higher but are still sufficient for most power loggers and meters.
They are ideal solutions for calibration laboratories, energy companies, and other organisations that manufacture and maintain energy meters, power quality analysers, etc.
In addition, there is the challenge of measuring electrical power and energy at high voltages and currents with a low power factor. This is becoming increasingly important from an economic perspective as a means of reducing costs in a continuously growing industrial economy. Nowadays, transformer buyers will impose economic penalties on a transformer manufacturer when losses are incurred in load and no-load conditions. In order to keep these losses as low as possible, the manufacturer must be able to measure them as accurately as possible.
Measurement International uses state-of-the-art, proven two-stage current comparator technology: the Acculoss™ Series transformer loss measurement system. This system is designed to meet the current needs of transformer manufacturers to achieve the most accurate transformer loss measurement system.
The measurements can be performed very accurately with the Yokogawa WT5000T, which was developed specifically for this application. The MI Acculoss™ unit can also be used for testing small, medium and large power transformers, as well as motors and turbines up to 400Hz.
In addition to this instrumentation, we also have transconductance amplifiers for higher currents, a phase angle meter from Clarke-Hess and highly accurate zero flux sensors from Signaltec (up to 5.000A).
