Megger supplies the CSU600A/AT range of current supply units.
These high current supply units have two main fields of application.
The first is to conduct primary tests on protective relays. A primary test shows whether all parts of the protection system are functioning together properly within the specified time limits under operating conditions.
The second field of application involves conducting current tests on low voltage circuit breakers and overcurrent devices.
The CSU600A current supply unit is a compact instrument which, together with Timer TM200 and an external ammeter meets stringent requirements for accuracy, easy handling and performance.
This current supply unit is ideal for:
- Performance and turn-ratio tests of current transformers
- Primary tests of protective relays
- Current tests on low- and high-voltage circuit breakers
- Commissioning tests that require variable currents
The sophisticated CSU600AT provides a more comprehensive solution. It has a built-in timer and an analogue ammeter that provide rough current settings quickly and easily. As a result, connection time has been reduced to the bare minimum.
The CSU600A and CSU600AT current supply units have an excellent weight/performance ratio.
