Products & Parts

GPT provides a comprehensive support service in the sourcing, manufacture and supply of spare components for rotating electrical machines and the associated static electrical & mechanical apparatus for Substations in the Power & Rail Industry.

We can offer “one-stop technical support service”, for inspection, diagnosis, maintenance, and replacement, which will be augmented with an optimal maintenance plan based on the results of the inspection and the diagnosis.

GPT carries parts from reputed, worldwide based, suppliers like ABB, Siemens, Larsen & Toubro, Arbiter, and we source for all OEM motors and generators.


Products from Arbiter Systems®, Inc. fall into three basic categories – GPS based precision timing clocks, synchronized power measurement products featuring synchrophasor measurement (PMU) compatible technology, and metrology based power measurement and calibration instruments. The power measurement and calibration products are supplemented with a complete line of standard and custom current and voltage test leads.

Timing and Frequency

Reliability and flexibility are the cornerstones of Arbiter’s industry leading precision timing devices. Reliabilty is achieved through a variety of methods: superior antenna and receiver technology, advanced algorithims and redundant services built on a communication protocol that supports multiple time sources in the event of satellite failure.

Customers demand both feature set functionality and products to match budgets. Arbiter’s line serves both, supporting advanced option capability that meet the toughest laboratory and sub-station applications, as well as low cost, highly accurate clocks that fit tight budgets.

Combining world-class accuracy with value pricing, Model 1094B delivers as standard the most commonly requested features for substation applications in Arbiter’s line of precision timing products.

Standard features include a 12 channel GPS receiver with typical accuracy to < ± 100 ns, two serial communications ports, and four standard outputs supporting both BNC and 5 mm terminal strip connections, selectable to output IRIG-B, 1 PPS or programmable pulse A or B functions.

Able to output 5 Vdc, the unit can easily drive multiple loads in parallel, including synchrophasors. GPS Data Back Up battery capable of maintaining the real-time clock, almanac and ephemeris data in the case of power loss.

  • Accuracy < ± 100 ns typical; < ± 250 ns worst case
  • Four outputs configurable for BNC or 5mm terminal strip connectors
  • One Form C (SPDT) fail-safe relay
  • Two RS-232 and RS-422/485 ports available
  • IEEE C37.118 compliant for Synchrophasor use.
