Title: Philippe Piney: Innovator in Electronic Trip Devices
Introduction
Philippe Piney is a notable inventor based in Villard Bonnot, France. He has made significant contributions to the field of electronic trip devices, holding 2 patents that showcase his innovative approach to circuit protection technology.
Latest Patents
One of Philippe Piney's latest patents is an "Electronic trip device comprising a correcting device." This invention features an electronic processing unit that issues a tripping order based on the root mean square (rms) value of the current measured by current transformers, along with the threshold and time delay setpoints. The device corrects the non-linearity of response from the current transformers, allowing for precise tripping in compliance with the current flowing in the circuit breaker. The type of correction is tailored to the circuit breaker rating, utilizing parameters obtained from tests and stored in the device.
Another significant patent is the "Circuit breaker with selective locking." This electronic trip device includes a mechanism for selecting faults that will trigger the locking of the circuit breaker contacts in the open position. When a fault occurs in the power supply system protected by the circuit breaker, the trip device orders locking if the fault is among those selected by the selection device.
