MPQ2000 - Monitoring a TT grounded system
Measuring the voltage between the ground and neutral provides an indication of the integrity of the ground connection. The poorer the connection (higher impedance), the higher the voltage between the neutral and ground conductors will be. During a fault, this level could rise over 50 V and become a serious hazard.

Total Demand Distortion (TDD)
Total Harmonic Distortion (THD) is a common method used to measure the level of waveform distortion.Total Harmonic Distortion (THD) measurements are an effective method of evaluating voltage distortion. However THD can be misleading when evaluating current distortion. THD is the summation of the harmonics presented as a percentage of the fundamental. For voltage THD this will be the summation of the voltage harmonics compared to the fundamental voltage. In a non-faulted condition voltage will always be present so a proper reference always exists.

Merging MPQ Data Files
Adding, removing or changing a piece of equipment in a facility can have significant impacts on the power quality and energy requirements. Introduced power quality phenomenon can cause equipment to trip off line. This can represent significant losses in revenue. Added equipment can create high peak loads or increased reactive currents that can lead to penalties. In order to determine the impact of these changes a power quality and demand study should be performed prior to the change and after the change.

Fast Transients
Very fast transients have limited energy due to their short duration. They are caused by arcing faults, such as bad brushes in motors, and are rapidly damped out by even a few meters of distribution wiring.

Enabling Additional Channels
When creating a setup file a particular power wiring connection needs to be selected. This instructs the instrument on how to calculate the power and energy. When the power wiring connection is create the required input channels are automatically enabled.In some cases the operator may wish to enable additional channels for other measurements. This will not affect the power or energy measurements.

EN50160 Report
The EN50160 test is a European standard that specifies the main characteristics of the voltage at a network user's supply terminal. The standard applies to public low voltage, medium voltage and high voltage AC electricity networks under normal operating conditions. In the UK, the test is known as a BS50160 test.
