SMC LET-500-VPC Grounding Circuit Measurements

×

The sets contain two distinct functions, the current injection and the voltage measurement.

The current regulation and production system consists of a continuous regulation autotransformer which drives a toroidal transformer designed for short-circuit duty so that the desired current is produced. This system of current injection makes possible to shift the current 180° in order to avoid possible stray current over the ground.

The voltage in step and touch measurement is made up with a digital voltmeter of 3 1/2 digits with a input designed so that the ohm resistance will be 1 KΩ. The precision of this set is ±1%.
 

Applications

These sets are designed to test ground circuit measurements, in what is called voltage in step and touch according to IEC standards used in some countries.
