Weidmuller has released its new Varitector Logger 20 to register and document large current pulses as well as the frequency and time of the incidents.
The plug and play product counts the current pulses greater than a set threshold value which are discharged by PE conductors on surge protection devices.
Any lightning strikes and surge voltages are continuously recorded.
Each measurement is issued with time a stamp accurate to the hour and the time and date of the event.
Using this information engineers can then design and implement appropriate systems as well as tweak existing ones to protect against surges.
For the accurate measurement of currents the Varitector Logger 30 features an external sensor with a ferrite toroid.
Clipped to the earth cable, this logger detects current peaks on the PE conductor which can be caused by events such as lightning or power surges.
A large two line LCD display provides the operator easy visualisation of current/incident data; while its buttons allow the menus to be easily navigated.
Weidmuller's Varitector Logger 30 also features a an internal CR123A replaceable 3-V battery with around four years of service life which allows the surge measurer to be connected to the mains at all times.
It complements Type-II and Type-III VPU surge protection devices, and can quickly and effortlessly be installed on the terminal rails in switch cabinets via its plug and play housing.
The logger has an operating temperature range of between -20 degrees and more than 60 degrees Celsius.
It also has a V-0 flammability rating.
