5.8. Spark5A 3 x 5A + partial discharge sensor.
This current sensor is designed for installations with
current transformers. Mostly the secondary of this
transformers is already connected to a metering or
control system. With this sensor this standard 5A or 1A
currents can be measured in an contactless manner.
Just put the 3 wires, though the holes of the sensor.
- Ranges:
o 20A rms fix input range
o 5A, 2A, 1A, 0.5A, 0,25A auto range for I1, I2, I3
In addition an ultrasonic microphone picks up the typical noise caused by partial discharge in
high voltage installation. Our proprietary algorithm splits up this noise in different bands, and
filters out the non 50 or 60 Hz related components.
A user should note that the detected level of partial discharge depends to the source
distance and acoustic properties of the room. So, not absolute level, but the level increase is
important to predict a potential explosion of the installation.
5.9. Placement
There are several possibilities to place the sensors:
- free hanging;
- fix with a cable tie;
- clicked on a DIN rail;
- attach to iron with the built in magnet.
5.10. Display with Touch Interface
The Volt1000 module has a display with touch interface. This allows to view the main
measurements and to alter the modbus settings.
There are several screens with measurements:
- Pt, It, In: total power (W), total current (A) and neuter current (A) for all attached
current sensors
- V, F: voltage (V) and frequency (Hz)
- I1..4, P1..4: current per phase (A), power per phase (W) per 3 current sensors
The settings screen shows the modbus address and baudrate. These can be altered and
saved.
The touchscreen distinguishes between short and long (>2.5s) touches. When touching the
screen longer than 0.5s, a progress bar at the top is shown as a visual aid.
The screen is enabled by touching it. It is disabled after no touches have been detected for
30s. It can also be disabled by a long touch in one of the measurement screens.
