Wires on current smart electricity meters are attached to the meter with screws. Installing with screws is a time-consuming procedure. Reliability is also a problem, because a person who installs wires, doesn't have a feedback if they are attached correctly. Master thesis is a result of a development process where fast clamps were integrated into the single- and three-phase meter in order to avoid the before-mentioned problems. Both of the meters with the integrated fast clamps were manufactered as working prototypes. Torque measurement for attaching wires was also made on one prototype.
