Lead Sets and Test Clips for Insulation Resistance Testers from Megger

Supplier News
article image Test Clips

Megger  supplies a range of lead sets and test clips of different sizes and electrical characteristics for use with Megger 5 kV and 10 kV insulation resistance testers.  

Meggers’s lead sets and test clips enable the user to choose the most applicable lead set for the work in hand.  

Lead sets are designed to facilitate connection to a variety of de-energised systems for the purpose of making insulation resistance measurements. The user is responsible for employing safe working practices and verifying that the system is safe before connection.  

Even isolated systems may exhibit significant capacitance, which could become highly charged during the application of the insulation test. This charge can be lethal and connections, including the leads and clips should never be touched during the test.  

The system must be safely discharged before touching connections.  

Megger’s lead sets are suitable for use with all current Megger 5 kV and 10 kV insulation resistance testers except the BM11, BM15 and MJ15.  

Large test clips

These clips are designed for clamping on larger diameter test pieces. The insulation is designed only to protect the user from the output of Megger 5 kV and 10 kV insulation resistance testers as well as systems below 1 kV to the prescribed category rating.  

The clips cannot in any circumstance be relied upon to protect the user from live systems above 1 kV AC.  

Dimensions: 220mm (L) X 134mm (closed)
Lead length: 3m
Jaw opening: 34mm diameter max.
Double insulation rating: 5 kV DC
Basic insulation rating: 10 kV DC
CAT rating: 1000 V AC CAT IV  

Medium test clips  

These test clips are designed for clamping on larger diameter test pieces in space-limited applications. The insulation is designed only to protect the user from the output of Megger 5 kV and 10 kV (set below 6 kV) insulation resistance testers.  

The clips cannot in any circumstance be relied upon to protect the user from live AC systems.  

Dimensions: 139mm (L) X 73mm (closed)
Lead length: 3m
Jaw opening: 34mm diameter max.
Double insulation rating: 3 kV DC
Basic insulation rating:
6 kV DC
CAT rating: 1000 V AC CAT IV    

Compact test clips

These clips are designed for clamping on test pieces where access is limited. There is no insulation on these clips. Extreme care must be taken to avoid electric shock when connecting/ disconnecting the bare metallic clips.  

Dimensions: 58mm (L) X 25mm (closed)
Lead lengths: 3m, 8m, 15m
Jaw opening: 18mm diameter max.
Double insulation rating: None
Basic insulation rating: None
CAT rating: Not applicable
