The three phase source and Reference (SR 33) is a portable electronic source, with built in reference standard. Based on a high power AMR processor and using a distributed intelligence throughout the system both reliability and durability is ensured, even in harsh environments.

A high power Relay Test Set, with optional built in controller (IPC). With 4 voltage and 3/6 current outputs and based on 32bit DSP technology, the RT46 provides high resolution dynamic testing of protection relays with accurate output monitoring via a built in digital recorder. Complete with a full range of software packages and optional end to end testing facilities, the RT46 is ideal for testing both electronic and electromechanical relays.
