ISA Advanced Test Systems
ISA Advanced Test Systems provides professional test and measurement equipment for power supply and grid installations — especially suited for testing and maintenance of transformers, instrument and power transformers (CT/VT), protective relays, circuit breakers, batteries, switchgear and other medium- and high-voltage components. The systems enable extensive tests such as primary injection, high-voltage tests, current and voltage measurements, protection function testing, grounding checks and comprehensive documentation and data management.
FAQ
What is ISA Advanced Test Systems used for?
The systems are used for commissioning, maintenance, periodic testing and diagnostics of transformers, circuit breakers, instrument transformers, relays, batteries and full substations or switchgear equipment.
Which testing methods are supported by ISA equipment?
Supported methods include primary current or voltage injection, high-voltage insulation tests, protective relay and function testing, grounding and earthing resistance measurement, current/voltage/power measurement, and testing of instrument transformers (CT/VT) and protection systems.
What does “primary injection test” mean?
Primary injection applies real or defined current/voltage through the actual network or circuit to test the behavior of the entire system — including transformers, relays and breaker coordination — under realistic load conditions.
What advantages do ISA test systems have over simple instruments?
ISA systems allow complex test sequences with high currents and voltages, test multiple components under real conditions, deliver documented and reproducible test results, and support full testing of protection and power systems rather than only isolated measurements.
How is data and test management handled?
ISA uses a dedicated software platform to control test sets, manage test data, store results, manage calibration and upgrades, and generate test reports — allowing standardized documentation and long-term record keeping.
For which voltage levels and types of installations are ISA testers suitable?
They are suitable for medium- and high-voltage systems, substations, switchgear, transformers, industrial power installations and grid infrastructure wherever strong currents, high voltages or protection systems are present.
When should tests with ISA equipment be carried out?
Before commissioning new systems, after modifications or maintenance, during regular inspections, or when troubleshooting, safety verification or compliance documentation is needed.
What must be considered when using ISA test equipment?
Strict adherence to safety protocols: proper earthing, isolation or de-energizing, correct configuration of test parameters, and qualified personnel. Proper interpretation and documentation of test results are also critical.
Who should perform ISA tests?
Skilled electrical engineers or technicians familiar with power systems, protection testing, relevant standards and safe handling of high-voltage test equipment.
What are typical application areas?
Utilities, grid operators, maintenance companies, industrial plants with medium/high-voltage systems, substations, transformer stations, switchgear test and commissioning services.
