Protection relays

Friday, 17 April, 2009 | Supplied by: Westek Electronics Pty Ltd


Protection relay testing instrumentation (ARTES series) is suitable for testing many types of protection relays, including distance, impedance, phase, earth/phase fault and synchronicity devices.

Analysis and testing control software provide an organised approach to testing and reporting.

The series is suitable for electronic and electro-dynamic/mechanical protection relays operating at generator, switchyard, transmission and distribution levels.

Circuit breaker testing instrumentation (ACTAS series) is suitable for testing single and multi-contact unit- and multi-pole HV, MV and LV breakers.

Extensive monitoring of operations includes coil current, contact travel, static and dynamic contact resistance, auxiliary contact operation. Analysis software provides testing control, analytical results and reporting.

The network monitoring instrumentation (Sherlog series) is designed for monitoring, including frequency stability, phase, harmonics, flicker, waveform faults, undervoltage, overvoltage, swells, sags and switching event recording.

The monitors may be combined in overall generator, transmission and distribution networks using GPS synchronising. Software packages provide analysis, testing control and reporting formats.
