Megger MGTR-II GPS timing reference

Description

Advanced Synchronization With GPS Timing Reference

The Megger MGTR-II GPS Timing Reference represents a leap in precision timing technology within the field of power system testing and protection. Engineered for exceptional synchronization, MGTR-II is a compact, lightweight, and field-portable GPS satellite receiver conceived specifically for end-to-end testing of line protection schemes. This device is an essential companion to the Megger relay test systems like SMRT, MPRT, and PULSAR, offering accurate trigger synchronization between devices separated by vast physical distances. Its robust construction and ease of deployment make it uniquely valuable for field engineers requiring high accuracy regardless of environmental challenges. As modern power systems become more interconnected and protection relays more intelligent, timing accuracy afforded by solutions like MGTR-II has become an operational necessity.

Outstanding Performance Ensured By Advanced GPS Receiver

At the heart of the MGTR-II is a state-of-the-art, twelve-channel GPS timing receiver. This core component allows the MGTR-II to simultaneously acquire and track all available GPS satellites, unlocking near-Cesium clock levels of timing accuracy within just minutes of startup. The device disciplines a high-performance ovenized crystal oscillator (OCXO) with GPS signals, delivering long-term accuracy up to 1 x 10–12 after 24 hours of tracking. Furthermore, the programmable output pulse (POP) delivers an impressive 100-nanosecond resolution, enabling precisely synchronized end-to-end testing. The MGTR-II also outputs a standard one pulse-per-second (PPS) signal, IRIG-B serial time code, and event time tag stamps, serving as a comprehensive time source for advanced relay test applications.

Unique Features Enabling Reliable Field Application

Designed for both rugged fieldwork and laboratory use, the MGTR-II comes encased in a robust enclosure, small and lightweight, easing transport and deployment. The supplied all-weather high-performance GPS antenna, with integrated low-noise preamplifier, is paired with a 50-foot (15.2 m) cable (or an optional 100-foot cable), ensuring high noise immunity and adaptability to challenging site conditions. Its intelligent Holdover™ feature provides near-Rubidium stability during temporary GPS outages, maintaining timing accuracy under adverse environments, such as urban canyons or near government installations, where satellite visibility fluctuates. The FastStart™ function ensures that within minutes of power-up, the MGTR-II achieves operational readiness, equipped to deliver precise time reference for the most demanding applications.

Exclusive Applications For Protecting Modern Power Grids

The MGTR-II is tailored for end-to-end relay testing, a critical application for utilities and grid operators. In such a scenario, precise timing signals are required to trigger geographically separated relay test sets—often hundreds of miles apart—within microseconds of each other. The MGTR-II’s programmable output pulse (POP) is configurable for specific time, date, polarity, and width, providing coordinated triggers for SMRT, MPRT, or PULSAR relay test systems. Additionally, the IRIG-B output supports synchronization of analog outputs across test sets using external protocols, and can be leveraged for testing time-accurate devices conforming to IEC 61850 or for phasor measurement unit (PMU) validation. The event time tag (ETT) feature enables high-resolution logging and archiving of external events, invaluable for protection engineers seeking to recreate and analyze complex fault scenarios.

Seamless Control With Versatile Communication Options

The MGTR-II is easy to set up and operate, supporting user control via a standard RS-232 serial port. Included Windows-based control software provides a user-friendly interface to configure output pulses, monitor status, and archive event data, even accommodating complex test scenarios. For device integrators and automation environments, the ASCII serial time message output further broadens the range of compatible test setups. Immediate error indication ensures engineers are quickly informed if precise time synchronization cannot be maintained. This seamless integration capability, through both the control software and straightforward hardware connections, makes the MGTR-II an indispensable part of any protection relay testing toolkit.

Built To Endure Harsh Field Conditions

In addition to performance, the MGTR-II is engineered for reliability under a range of environmental stresses. The main device operates in temperatures spanning from -20°C to +70°C (14°F to 158°F) and is built with a rugged enclosure that withstands the rigors of field deployment. The GPS antenna is fully weatherproof, enabling operation in extreme climates, from -45°C to 85°C (-11.2°F to 158°F), and maintains reliable connectivity even in high humidity (up to 95% RH for the main unit). Accessories include a sturdy 4-inch antenna mount and an optional soft-sided transit case for extra protection and convenience.
