Measure your system without disturbing it
The engineers need precise floating voltage measurement heads, connected through optical fiber for a multi-kV insulation, with a large bandwidth, a good rejection of the common mode noise, and with reasonably small dimensions. It shall be able to perform simultaneous synchronous real time measurements on multiple parallel channels. The measurement probe and optical transmitter shall be well immune to external electromagnetic field noises.
Montena MOL25T and MOL500T are fibre optic analogue transmission system with small, shielded remote access modules ideally suited for measurement of floating voltage fast transients in disturbed electromagnetic environment. The shielded, battery-operated remote module converts the measured electric signals into an analog optical signal and sends it to the optical receiver module through a standard single mode fibre optic cable.
Key facts :
- Unsurpassed immunity to electromagnetic fields
- Remotely selectable transmission gain
- Optical fiber cable provides total galvanic isolation
Measure your high-voltage installation in complete safety
Measurements in high-voltage environments often pose the problem of bringing the equipment close to the measurement point and at a high floating potential, with all the safety aspects that this entails. This issue can be easily solved by using an optically isolated measurement probe. The optical fiber ensures total galvanic isolation between the measurement point and the operator.
Montena MOL25T and MOL500T are fibre optic analogue transmission systems with small, shielded remote modules, ideally suited to the real-time measurement of DC and high-frequency signals at measurement points up to 1km apart.
Key facts :
- Battery powered point-to-point modules, or up to 10 slot chassis with plugin modules
- Remotely selectable transmission gain
- Fiber optic link up to 1km long
