One of the significant features of this model is the D-Lok circuit kylritsu permits loop impedance testing without tripping some types of RCD installed in the circuit being loop tested.
KYORITSU A : User guide
The Kyoritsu A loop impedance meter has automatic lock-out if test resister overheats. The cause of the fault must be investigated and rectified. This mode is cancelled whenever the test button is pressed. In the event of a fault, the Fault loop impedance should be low enough and the Kyorittsu Fault current higher enough in order to have the automatic disconnection of supply by the installed protection device within prescribed kyoitsu interval.
Page 14 The figure below shows in marked line the Fault loop impedance for TN system. Loop impedance measurement is important in preventing accidents caused by the earth leakage breaker and other protection devices to becoming inoperative.
If not, disconnect from the mains and check the wiring at the socket. The figure below shows in marked line the Fault loop impedance for TN system. Contact Us Order Status. This advantage over many other loop impedance meters means there is no need to by-pass many RCD tyoes at distribution boards, when conducting Loop or PSC tests. Rating A 6 10 16 20 25 32 40 50 63 kjoritsu Disconnecting time 5s Disconnecting time 0. Every circuit must be tested to make sure that the fault loop impedance does not exceed that specified for the over current protection device concerned.
Get the item you ordered or get your money back. This occurs when the earth circuit is overloaded or shorted and sufficient current does into flow into the circuit where the loop impedance is too high.
