SMCS-JW1001
CURRENT SENSOR (0.72-3KV)
This type is designed for simple original equipment in switchgear. It is slide on the not mounted output T-connector in the substation. When the connector is screwed on the feed through, its sheathing expands. Thus, the sheathing presses against the inner surface of the current sensor and fixes it. Consequently, additional fixations of the sensor in the substation are not necessary.
Due to their small size, up to three sensors can be mounted in a cable compartment with a width of 300mm and a phase distance of 95mm.
SMCS/T-JW1002
CURRENT SENSOR (0.72-3KV)
The retrofit application in existing installations is the primary field of application for this type. The click system enables a tool-free mounting of the sensor on site. Dismounting of the T-connector is not necessary, since the sensor is enclosing the cable.
The sensor is delivered with two cable straps to fix it directly on the output cable. The cut surface of the iron core and a sophisticated spring system in the sensor housing ensure that the measurement precision of the sensor is guaranteed after assembly on the output cable.
SMCS3-JW1004
CURRENT SENSOR (0.72-3KV)
Multifunctional Current Sensors
(phase current and earth fault detection) :
The current sensor in 3-phase design combines maximal flexibility with maximal functionality. It is possible to add the earth fault detection to the three single phase converter in the sensor.
In addition to the extended version, consisting in three current sensors and a sensor for the earth fault detection, different simpler layouts can be provided in accordance with customers´ requirements. This sensor is designed for original equipment in switchgears.
GAE 120/SENS-JW1003
CURRENT SENSOR FOR EARTH FAULT (0.72-3KV)
Sensors for Earth Fault Detection
The sensor for earth fault detection of type GAE120/SENS is based on a market proven and established product. All output cables of the substation are conducted through this transformer.
In case of earth fault in a three-phase network, a current occurs due to the displacement of the neutral point. This current is implemented with a specific ratio in the output of the sensor. Therefore the system enables to detect fault and short-circuit currents.
