Description

Grounding Circuit Measurements

Instrument for grounding circuits measurements
This range of equipment is designed to test grounding circuit measurements in substations and transformer centres, in what is called voltage contact in step and touch according to IEC standards used in some countries.

Instrument for grounding circuit measurements.
Model S-LET-60-VPC
The set contains two distinct functions, the current injection and the voltage measurement.
In the injection of current, a variable autotransformer of current regulation is connected to a current producer transformer with various ranges of output. The current produced is measured with a shunt system connected to a digital instrument. 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 KV. The precision of this set is ±1%.

APPLICATIONS
– This set is designed to test ground circuit measurements, in what is called voltage in step and touch according to IEC standards used in some countries

CHARACTERISTICS

-Accessories for measurements incorporated.
– Inversion of current output.
– Regulation: 0-60A / 6KVA.
– Current measurement: ±0,5%.
– Voltage measurement: ±1%.
