Products
PMCS1 – Protection Cable Earth Fault
Products family : Feeder Protection Sector : Transmission The PMCS1 is an overcurrent protection with 2 thresholds for the protection of EHV cables: – The first low delay threshold (“sheath mass”) issues an alarm, without tripping. – The second high threshold (“Ground Cable”) causes an instantaneous trip.
PMLS355 – Line Overload Protection
Products family : Feeder Protection Sector : Transmission The line overload protection PMLS355 thresholds have 3 and 5 plans (designation 35). If prolonged exceeded one of these thresholds by the current line I command the circuit breaker protection associated with the line.
PMLS25D / PMLD2500 – Power Flow Protection
Products family : Feeder Protection Sector : Transmission The PMLS25D PMLD2500 protections and allow the unwinding of a high voltage network on a current measurement criterion when changing the direction of flow of power. Two alarm and trip thresholds are available, as well as five seasonal patterns.
DRSN1 / DRSN100 – Power Swing Protection
Products family : Voltage Protection Sector : Transmission Some lines 400 kV and 225 kV transmission network interconnect the power plant generators allowing them to remain synchronous: they are a synchronizing link. Worldwide, some major incidents have resulted in production losses of synchronism groups then GENERATE voltage beats on interconnection links; they could have significant…
ATRS11B – Recloser for EHV & HV networks
Products family : Feeder Protection Sector : Transmission ATRS is a dedicated recloser for HV or EHV. Its numerous optional functions allow operation on various networks. RTE, Réseau de Transport d’Electricité in France, has qualified ATRS as its only reclosing device.
TMS7003 / TMS7004 – Under and Overvoltage Relays
Products family : Voltage Protection Sector : Industry The optimum operation of an electrical network depends particularly on the reliability and the availability of the protection, measuring and automation devices, and the way these devices can communicate their informations. TMS 7000 relays are designed to monitor the voltage of three phase electrical networks either balanced…
Acoustic Emission Diagnostic and Monitoring of Power Transformers
Power transformers account for the largest portion of capital investment in transmission and distribution substations. Failure of a single power transformer carries a multimillion-dollar impact with a build or replacement timeline of18-24 months. Yet 53 percent of transformer failures are preventable. But what if there was a way to protect that substantial investment while safeguarding…
SUBSTATION ACOUSTIC EMISSION WIRELESS SENSORS
APPLICATIONS ON POWER EQUIPMENT Acoustic Emission (AE) Wireless Sensor Nodes This system together with its sensors is applicable to the monitoring of medium and high voltage equipment such as transformers, circuit breakers, CT’s, VT’s, GIS, bus bars, etc. The main purpose of having Power Circuit Breakers on the substations is to protect the equipment from…
