Basic Three-phase Protection Relay Test Set

Model: HME-702

The HME-702 is a basic and economical protection relay test set with three-phase current outputs and four-phase voltage outputs. The HME-702 kit can apply to the testing not only on operating value and operating time of AC/DC relays, but also on complex voltage blocking directional over-current, zero sequence over-current, low-frequency load shedding and other protection functions of low voltage micro-processor based protection and whole group transmission of high voltage micro-processor based protection, and on starting value, quick-break value, harmonic blocking value and micro-processor based transformer differential protection.

The Basic Three-phase Protection Relay Test Set HME-702 has dual operation mode. It can be operated in local mode without PC, also can be controlled by software running on a PC after connecting to PC via communication cable.
