Disruption suppressor in a measuring interface

摘要

A perturbations suppressor for measurement interfaces comprising two protection stages, both for the three phases and for the neutral, configured for each phase and for the neutral with a resistor (3) with a high ohm value and a high power, a varistor (5), a second resistor (4) for uncoupling power and a voltage limiter (6), having an earth connection (7) and terminals (1) for connection to the 220v power input and a terminal (2) for connection to the equipment.
