MGTR-II Megger GPS Timing Reference-Mark II
■The MGTR-II is a small, lightweight, field portable, GPS satellite receiver system specifically designed to perform end-to-end tests of line protection schemes, with Megger SMRT, MPRT and PULSAR relay test systems. The MGTR-II provides a precise programmed output pulse (POP), with 100 nanoseconds of resolution. This output pulse provides a trigger synchronization of two or more SMRT, MPRT or PULSAR test systems to less than ±1μ Sec of the Universal Time Coordinated (UTC).
■The MGTR-II consists of a twelve-channel GPS timing receiver integrated with proprietary microprocessor-controlled timing and interface logic The MGTR-II simultaneously tracks all available GPS satellites The microprocessor-controlled timing and interface logic derives precise timing information. In addition, the MGTR-II provides a standard 1 Pulse Per Second (PPS), and ASCII serial time message, external event time-tag, an IRIG-B serial time code output signal and most importantly, a programmable output pulse for performing end-to-end tests.
■The unit comes with a 50 foot (15.2 m) long cable and all-weather, high-performance, high noise immunity antenna with an integrated low-noise preamplifier. The antenna comes with a 4 inch tall antenna mount.
■Control of the MGTR-II is through a standard RS-232 serial connection. Software is provided to communicate to, and control the MGTR-II unit
●FEATURES AND BENEFITS
■Programmable Output Pulse (POP) - Used to trigger the end-to-end tests using Megger PULSAR, MPRT, or SMRT relay test sets. The POP can be specified by date, time, repetition (single pulse, or multiples), pulse polarity, and pulse width with 100 nanoseconds of resolution.
■External Event Time Tag (ETT) - Used to mark date and time of an external event with 100 nanoseconds of resolution Multiple events are buffered, and the control software allows events to be archived.
■State-of-the-art 12 channel GPS technology -
Capable of tracking up to 12 satellites simultaneously
■Intelligent Holdover™- provides near-Rubidium holdover characteristics in the absence of GPS signals. This allows high accuracy triggering even when not receiving GPS tinning signals. This provides end-to-end test capability in high foliage, mountainous, urban canyon environments and near government facilities where GPS signals may be temporarily blocked
■FastStart™- Offers high accuracy within minutes of start-upz which provides faster time to first test.
■IRIG-B Output- Provides precise time outputs in the industry standard IRIG-B format. Used for synchronizing outputs for end-to-end tests, provides time stamping for IEC 61850 sampled values, or for testing phasor measurement units (PMU).
■GPS Disciplined Ovenized Crystal Oscillator - insures the highest accuracy possible for triggering end-to-end tests.
■Windows® Based Control /Software - Provides simple user interface to set the Programmable Output Pulse for end-to-end tests.
■100 nanosecond Accuracy - Insures the highest available accuracy for synchronized end-to-end tests
■RS-232 serial port - The RS-232 port provides a computer interface to perform automatic testing.
■Immediate error indication - Visual alarm in di cates when unit cannot supply corrected precise time due to loss of GPS signals.
