The maintenance of an adequate low resistance ground connection is essential to both the protection and performance of any electrical system. Ground testing should be performed both upon installation, to meet design specification, and periodically thereafter in order to maintain service.
The Megger DET4TCR2 Ground Resistance Test Kit can perform bonding tests (using an ac signal), to determine that adequate connection has been made from equipment to the grounding system, and can perform soil resistivity tests.
