Abstract: A Rogowski sensor is provided for measuring a current of an electrical conductor. The sensor has a Rogowski coil, which has an electrical winding resistor, and an integration device which is connected to the Rogowski coil and is intended to generate an output signal which is proportional to the electrical current to be measured by the Rogowski sensor. The integration device is formed by the winding resistor of the Rogowski coil and a capacitance which is connected to the two winding connections of the Rogowski coil, and for the output signal from the integration device to be formed by the voltage applied to the capacitance.

Abstract: A circuit breaker pole for interrupting the electric current is insulated by a solid material and has a dimensionally stable and electrically non-conducting insulating material housing, a switching tube fastened in the insulating material housing and having a stationary fixed contact and a movable mobile contact. An input connection piece is electrically connected to the fixed contact and contactable from outside, and an output connection piece is connected to the mobile contact via a movable contact connection. The output connection piece is linked with the insulating material housing in a fixed manner and has a contact surface that can be contacted from outside. The insulating material housing has an opening for inducing a driving motion into the movable contact. The mobile contact connection is fixed to the output connection piece by connecting devices that act upon the contact surface. The circuit breaker pole is inexpensive and easy to install.

Abstract: The invention relates to a method for producing a circuit-breaker pole (1), insulated by a solid material, said pole comprising an actuator opening that is configured to introduce an actuation displacement. According to said method: a switch (2) comprising a switch housing (3), which has an actuation face (8), through which a drive rod (9) is guided and a dimensionally stable jacket (7) consisting of insulation material and provided with a connection part (6) are produced independently of one another; the switch (2) is fixed in the jacket (7) in such a way that the switch housing (3) excluding the actuation face (8) and the jacket (7) that is provided with the connecting part (6) delimit a gap which opens towards the actuation opening; the gap is subsequently filled with a fluidic compensating mass (10) and finally said mass (10) is cured. The invention also relates to a circuit-breaker pole (1) comprising a potting channel, for interrupting an electric current.

Abstract: A filter system and a method for cleaning a gas laden with powder particles, in particular for a powder coating apparatus. At least one filter element is arranged between a crude gas chamber and a clean gas chamber. A first gas discharge device directs a gas stream from the crude gas chamber through the filter element into the clean gas chamber. A shut-off device interrupts the first gas stream through the filter element, and a second or cleaning gas discharge device directs a cleaning gas stream through the filter element into the crude gas chamber. A vibration device vibrates and/or shakes the filter element to dislodge powder from the filter element.
