Description

The circuit breaker tester CBPOB30D is a power supply unit employing the latest power electronics technology. The circuit breaker tester CBPOB30D generates ripple free DC-voltage and it is developed for regular maintenance tests of power circuit breakers. Output voltage is selectable from 10V to 300V DC. The circuit breaker tester CBPOB30D is powerful and versatile unit, with possibility to generate at 230V mains supply initial current up to 35A as well as continuous current according to the table below:

Load voltage	Mains voltage	Max Current	Max load
48V	230V	32A 26A 22A 10A	2sec 30sec 90sec continuously
	115V	32A 26A 22A 10A	2sec 30sec 90sec continuously
110V	230V	30A 24A 20A 9A	2sec 30sec 90sec continuously
	115V	18A 14A 12A 5A	2sec 30sec 90sec continuously
220V	230V	15A 12A 10A 5A	2sec 30sec 90sec continuously
	115V	9A 7A 6A 3A	2sec 30sec 90sec continuously

The set is equipped with thermal and overcurrent protection. The circuit breaker tester CBPOB30D is easy to use and has accessory cable-set with touch-proof contacts. The CBPOB30D has very high ability to cancel electrostatic and electromagnetic interference in HV electric fields. It is achieved by very efficient filtration. The filtration is made utilizing proprietary hardware and software.

Applications:

The circuit breaker tester CBPOB30D is developed for use in switchyards, electric power and industrial environment. An important part of commissioning and maintenance testing is a circuit breaker testing. The circuit breaker tester CBPOB30D is possible to use for:

• minimum trip-voltage test of the circuit breaker's coils
• supplying spring-charging motors
• power supply at test with breaker analysers

The circuit breaker tester CBPOB30D have built-in capability to perform an automatic test of minimum trip-voltage. The minimum trip-voltage test is described in a number of international and national standards such as IEC 62271-100, ANSI C37.09 etc.
Many other important parameters are possible to test with a breaker analyser. CBPOB30D is then used as a power supply unit. It is compatible with breaker analysers from different vendors. CBPOB30D can also be used as a general power supply unit or a temporary battery charger.

Automatic testing of the minimum trip voltage of a breaker

Procedure steps

• 1. Make certain that the mains are de-energised on both sides of the breaker, safety grounded and that local safety regulations are followed.
• 2. Connect Power supply unit CBPOB30D to the breaker's coil circuit.
• 3. Set the minimal test voltage.
• 4. Set the step voltage.
• 5. Set the maximal voltage.
• 6. Press TRIG button.
