Megger MGTR-II GPS Timing Reference

Megger MGTR-II GPS Timing Reference

The Megger MGTR-II is a small, lightweight, field-portable GPS satellite receiver built to perform end-to-end tests of line-protection schemes together with Megger SMRT, MPRT and PULSAR relay test systems. It generates a precise programmed output pulse (POP) with 100 ns of resolution, giving test teams at both ends of a line a common, satellite-locked time reference so tripping and communication times can be measured accurately across substations. A 12-channel receiver reaches 100 ns timing accuracy within minutes of start-up and holds near-rubidium stability if the GPS signal is briefly lost, making it dependable for demanding field protection testing.

Key features of the Megger MGTR-II GPS timing reference

• 100 ns programmed output pulse (POP) – programmable trigger pulse with 100 ns resolution synchronises relay test sets at both ends of a line for true end-to-end testing.
• 12-channel GPS timing receiver – tracks all available satellites and reaches 100 ns accuracy within minutes of start-up, synchronised to better than ±1 µs of UTC.
• Near-rubidium holdover – maintains near-rubidium timing stability during temporary loss of the GPS signal, so tests stay valid in weak-signal locations.
• Multiple time outputs – 1 pulse-per-second (PPS), IRIG-B time code, ASCII serial time message and external event time-tag support a wide range of schemes.
• Works with Megger relay test systems – designed for use with Megger SMRT, MPRT and PULSAR relay and protection test sets.
• RS-232 interface and Windows software – standard serial connection with Windows-based control software for simple set-up and programming.
• High-performance antenna – all-weather, high-noise-immunity antenna with integrated low-noise preamplifier and a 15.2 m (50 ft) cable for flexible placement.
