Technical aspects affecting the use of insulation fault location systems 6.3.4 EDS systems with switching function Characteristics of switching function: • All measuring channels are scanned in parallel during insulation fault location.• The max. scanning time is ≤ 10 s. • At the end of this time the relay contact switches the faulty measuring channel concerned.• This switching contact can be used to disconnect the faulty outgoing circuit via a contact element.
