The World's Fastest Power Cord Tester
With reference to ASTA, BSI and other regulatory body requirements, it has become standard practice supply mains powered electricals products with pre-wired cord sets fitted with either moulded-on or re-wireable connectors.
In response to cord set manufacturer requirements, for a production line tester to ensure 100% build integrity and electricals safety of their product, Clare developed the Mains Cord Test Set. This instrument, when coupled with a dedicated test enclosure, can provided complete test cycles of 3 seconds and will check Earth continuity, Line and Neutral continuity / polarity, insulation between all cores and between cores and outer surfaces of plug tops and other fitted connectors.
Earth Bond Resistance
High current injection (variable 0-30 Amps) through the Earth conductor
Continuity
Low voltage d.c. through Line and Neutral conductors
Polarity
Applied simultaneously with the Continuity test
Flash Test Ln-E
0-2.5kV a.c. from Line and Neutral conductors to the Earth conductor
Flash Test L-N
0-2.5kV a.c. between Line and Neutral conductors
Flash Test LN-Plug Surface
0-5kV a.c. from Line and Neutral conductors to outer surface of plug top
Leakage
Monitored at Flash Test voltage - nominal trip equivalent to 5 Megohms
The tester can also be set for 2-core lead sets, with the Earth test being replaced by a sensing circuit to detect the presence of a 3-core lead if incorrectly loaded.
