| Powerful DC and AC power supply for a circuit breaker test |
| Description |
POB30AD is a power supply unit employing the latest power electronics technology. POB30AD generates ripple free DC-voltage and it is developed for regular maintenance tests of power circuit breakers. POB30AD generates also AC voltage. Output voltage is selectable from 10 V to 300 V DC or from 10 V to 250 V AC.
The POB30AD is powerful and versatile unit, with possibility to generate at 230 V mains supply initial current up to 30 A as well as continuous current according to the tables below: |

The set is equipped with thermal and overcurrent protection. POB30AD is easy to use and has accessory cable-set with touch-proof contacts.
The POB30AD 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 |
| POB30AD is developed for use in switchyards, electric power and industrial environment. An important part of commissioning and maintenance testing is a circuit breaker testing.
POB30AD is possible to use for: |
- operating circuit breakers
- supplying spring-charging motors
- power supply at test with breaker analysers
- minimum trip-voltage test of the circuit breaker's coils
|
| POB30AD 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. POB30AD is then used as a power supply unit. It is compatible with breaker analysers from different vendors. POB30AD 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 POB30AD 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. |
