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.

Measuring operational low voltage networks
Low voltage cable faults are often unstable, so they can only be located when the cable is conducting live voltage. Testing under these conditions is extremely hazardous, so separations filters, as well as constructional safety methods, should be employed at all times.

Mains Signalling
Power-line communication (PLC) carries data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers. It is also known as power-line carrier, power-line digital subscriber line (PDSL), mains communication, power-line telecommunications, or power-line networking (PLN).

Low voltage network structures
Low voltage networks are a huge national investment, under daily pressure to give out power for hours at a time to a plethora of electrical appliances. It is therefore essential that their cables and transformers are tested often to prevent outage. To effectively test the components in low voltage networks, it’s important to know the different types of systems within them and how they are structured.

Intro to fault location in low voltage networks
Fault occurrences in medium voltage networks are usually covered by redundancy in the system which, with appropriate switching, usually ensures a relatively uninterrupted continuation of the supply for the customer. A lengthy wait until the fault can be corrected only results in the increased risk of a second failure in this area, creating a customer outage that cannot be restored by switching.

Examples of fault location
In branched low voltage networks, low-resistance faults, interruptions and large changes in impedance can only be located by comparing fault-free and defective cores.

ETK (Earth Test Kit) for Earth (Ground) Testing
When considering earth (ground) testing, people will often ask about what type of test leads should be used. This includes questions about the type of wire used, the resistance of the leads and the length of the leads, as well as concerns over safety. Fortunately, most of the answers to these questions are addressed by the design of the earth tester itself.

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.
