The NOJA Power OSM38 auto recloser from NOJA Power Switchgear has been successfully type tested at KEMA in The Netherlands.

Over a period of two weeks, KEMA conducted a full set of IEEE C37.60 and IEC 62271-111 type tests on the OSM38 product.  

These tests included interruption duty cycle at 12.5kA, short time current 12.5kA 3 seconds, load switching 630A, cable charging, line charging, dielectric withstand capability including 170kV BIL across the open gap and 195kV BIL phase to phase and phase to ground, wet and dry power frequency, temperature rise as well as mechanical operations testing.  

A single sample was used for all interruption and load switching testing while a second sample was used for impulse and temperature rise testing.  

The NOJA Power OSM38 product passed all certification testing processes and KEMA is now in the process of issuing three complete type test certificates to confirm the successful testing and full standards compliance.
