The MLLA is a low-voltage source modeling device with Rogowski coil. It provides filtering of low-level outputs. It can be used with any device from the SMRT or FREJA 500 series (in conjunction with SMRT/FREJA hardware version 3.51 or higher, with a minimum firmware version of 6.150 and RTMS D100.53 driver version or above).
There are three Rogowski voltage output ranges: 2 V, 10 V, and 40 V. The millivolt output in the low-voltage range offers high resolution and accuracy.
The Megger low-level adapter MLLA is designed to filter low-level outputs from the latest Megger series SMRT and FREJA 500 voltage/current generators. In Rogowski mode, current channels are converted from current source to millivolt source, allowing the current channel to simulate a low-level voltage source from the Rogowski coil, and MLLA can filter these low-level outputs.
There are three Rogowski output ranges: 2 V, 10 V, and 40 V. In low-voltage mode, the voltage channel provides from 0 to 2 V with high resolution and accuracy. Use the low-level outputs available on the latest versions of SMRT and FREJA relay test sets to test relays that use low-voltage signals from unconventional current transformers (CT) and voltage transformers (VT), such as Rogowski coils and variacs.
Current and voltage channels can be configured to simulate low-level outputs via RTMS software control on the SMRT or FREJA 500 device. Low-level outputs are accessible from the voltage and current channel terminals through separate MLLA low-level filters. For testing relays like ABB REF615 and Siemens 7SJ81, the low-level filters provide an interface between the converted low-level relay test set terminals and the low-level signal interface cables to the tested relay.
