Serbia Single-Sequence Current Protection Tester

The HXOT SPRT750 and Megger SVERKER 650 are leading single-sequence relay protection testers suitable for field and lab use in Serbia.HXOT SPRT750 OverviewThe HXOT Single-sequence Relay Protection Tester SPRT750 is designed for precise testing of single-phase relay protection systems in power plants, substations, and industrial environments . Key features include:Output Circuits: Two independent circuits providing AC currents up to 100A, AC/DC voltages up to 300V, and DC currents up to 10A.Protection Functions: Supports overcurrent, undercurrent, time-delay, and voltage protection testing.Applications: Suitable for power systems up to 35kV, including plants and mines.Design: Portable, user-friendly interface, and convenient for on-site testing.Control: Milliseconds and metered output control for precise measurements.Megger SVERKER 650 OverviewThe SVERKER 650 is a compact, high-precision single-phase relay test set ideal for secondary injection and primary testing . Highlights include:Current Output: Up to 100A for single-phase testing.Testing Capabilities: Supports virtually all single-phase protection, directional relays, and phase-shifting systems.Design: Rugged, transformer-based construction suitable for extreme climates, portable, and easy to operate without a PC.Accessories: Includes test lead sets, transport case, and optional ACA120 voltage source for directional relay testing.Applications: Electrical distribution substations, renewable power generation stations, and industrial environments.Comparison and SelectionHXOT SPRT750 is ideal for field testing in plants and mines with flexible output circuits and real-time data monitoring.SVERKER 650 is more compact and robust, suitable for high-voltage substations and environments requiring portability and reliability.Both testers allow single-phase protection testing, with the SVERKER 650 also supporting sequential testing of three-phase systems one phase at a time. For users in Serbia, both devices are suitable for ensuring relay functionality, safety, and compliance with operational standards. Selection depends on the specific application, portability needs, and output requirements.
