Product Description
Overview
In power system of ***6KV, when capacitive current associated with
single phase ground fault excess *0A (It is *0A in ***0KV cable
circuit system), arc suppression coil device should be adopted to
prevent arc grounding, remove earth fault and improve power supply
quality.
MRD-XHZ Arc-Suppression Coil with Adjustable Tuning Compensation
Device employs standard industrial computer system,
bus-organization, multilayer PCB and full-color LCD screen to
provide system with stable operation, visual display, strong
anti-interference capability, perfect parameter settings and
information query function.
MRD-XHZ Arc-Suppression Coil with Adjustable Tuning Compensation
Device adopts ****0KV voltage grade and is widely used in
transformer substations of large factories and mines.
Features
- Controller adopts industrial computer platforms, dual-CPU
framework and multilayer PCB processing to ensure stable and
reliable operation
- With full-color LCD screen, the running state, system
capacitive current, neutral voltage, neutral current,
out-of-resonance degree, residual current and fault-times of
single-phase can be displayed, set and inquired conveniently
- The adjusting range is wide, between ****0% rated current and
also accurate and quick
- Embedded high voltage grounding line selection module employs
residual incremental method and active power method making the line
selection accurately and quickly
- Equipped with RS**2 and RS**5 communication interface, our
product can communicate with supervising computer to achieve signal
teleportation
- Our product can realize acoustic alarm of single-phase earth
fault
- Equipped with standard parallel printer, our product can finish
data printing and ground information printing
- Our product possess one system controlling two sets device
function, namely, two sets of arc suppression coil in the same
system can transform automatically along with the system
operation

Ordering data
- System voltage grade: 6KV, *0KV, *5KV
- Arc Suppression Coil capacity
- The capacity of arc suppression coil is determined according to
the size of the capacitive current under the single-phase grounding
fault and should have a certain margin
- The grounding transformer capacity
- the quantity of zero sequence current transformer
Attention!
Please ensure good grounding system of the device and make
different access to the ground network for the cabinet and the
device. In dry areas, the ground network resistance should be
measured regularly to make sure the ground resistance less than
4
Ω
to prevent burning loss.
