Megger FOS1 Fiber Optic Transmission System

Description

Advanced Fiber Optic Transmission: Unparalleled Signal Integrity

The Megger FOS1 Fiber Optic Transmission System is a distinctive solution for reliable, high-fidelity transmission of analog signals. This system employs advanced fiber optic technology, enabling the secure transfer of measurements in environments where electrical noise or hazardous voltages render traditional cabling impractical or unsafe. With its capacity to handle analog signals from DC up to 10 MHz, the FOS1 ensures a broad range of industrial, laboratory, and utility measurement needs are met precisely and without interference. Designed to deliver amplitude-modulated infrared light through optical fibers, Megger’s FOS1 converts sensitive signals into light, transmits them with loss compensation, and reconstructs them accurately at the receiving end. Every critical parameter—from system sensitivity to signal fidelity—is rigorously maintained for uncompromised data integrity. The outstanding performance, flexibility, and adaptability of the FOS1 make it suitable for both demanding everyday laboratory use and intricate field testing requirements.

Principle of Operation: From Voltage to Light Transmission

The operating principle of the FOS1 Fiber Optic Transmission System revolves around converting electrical measurement signals into modulated light, transmitting these through an optical medium, and then reverting the light to voltages at the receiver. The system comprises three main elements: a transmitter, an optical fiber, and a receiver. The transmitter receives signals—these could originate from shunts, dividers, or specialized sensors—which are then used to modulate an infrared light source. This modulated light is transmitted along the fiber to the receiver, where demodulation and voltage reconstruction occurs with precision. Automatic or semi-automatic compensation mechanisms for fiber attenuation are included, guaranteeing measurement consistency despite long fiber runs or minor losses. The system’s built-in detection and indication mechanisms also ensure users are immediately notified of any violation of the dynamic signal range, boosting troubleshooting efficiency and operational reliability.

Multiple Applications: Precision Across Diverse Measurements

One of the prime strengths of the Megger FOS1 Fiber Optic Transmission System is its versatile range of application scenarios. In power diagnostic setups, FOS1 is invaluable for analog transmission in high-voltage isolation measurements where electrical separation is critical for safety and accuracy. Within industrial automation, it’s ideal for safely connecting sensors and actuators across electrically noisy or hazardous sites. The system provides specialized support for both low-impedance and high-impedance piezoelectric pressure measurement, addressing the full spectrum from voltage-mode to charge-mode sensors. Acoustic partial discharge analysis in high-voltage environments is enabled by using FOS1 with compatible sensors and switchable supply circuits, supporting effective condition assessment of critical assets. Displacement measurement is another important application, as FOS1 can precisely relay outputs from potentiometric or rotary position sensors for remote monitoring or closed-loop control systems—valuable in test rigs, process automation, and research settings.

Remote Operation and Sensor Interface Flexibility Enhanced

A standout feature of the FOS1 system is its remote start capability. This function, implemented via an additional optical fiber, allows operators to switch transmitters from a low-power standby state into active measuring mode using optical pulse telegrams, an essential tool for scenarios where equipment is difficult to access or needs to remain in an energy-saving condition for extended periods. Standby times of several years are possible, maximizing operational flexibility in distributed or intermittently monitored systems. On the signal interface side, the FOS1 offers unique options: not only can it transmit passive sensor, shunt, or divider signals, but it also accommodates active sensors with integrated power supplies. This level of interface versatility means users can adapt the FOS1 system for a wide range of sensor types and measurement requirements without cumbersome rewiring or additional equipment.

Acoustic and Piezoelectric Sensor Support Detailed

For measurements involving acoustic partial discharge sensors—namely the AS75I and AS150I—working at high voltage potentials, FOS1 transmitters can be fitted with switchable supply circuits providing 15 V or 28 V as needed. This is critical to achieve the required sensitivity and enable proper operation of the sensors. Furthermore, for pressure sensing applications, FOS1 supports both low-impedance piezoelectric (voltage-mode) and high-impedance piezoelectric (charge-mode) sensors. For voltage-mode sensors, an optional constant-current source supplies the necessary current to the built-in FET amplifier, enabling accurate signal conversion and transmission. For charge-mode sensors, a built-in preamplifier with precisely matched gain and built-in overvoltage protection up to ±40 V interacts seamlessly with specific sensors, such as those manufactured by Kistler, supporting multiple selectable pressure ranges. This ensures FOS1 can handle even the most sensitive and highly specialized sensor measurements without external signal conditioning.

Displacement Measurement and Accurate Signal Supply

In scenarios requiring displacement measurement, such as the monitoring of rotary or linear position transducers, the Megger FOS1 system provides facilities for accurate signal supply and conditioning. This includes an option for a dedicated 5 V output to power position transducers, with intelligent sequencing control: before supply voltage is delivered, the system activates DC adjustment to guarantee accuracy and prevent signal drift or error from improper initialization. This meticulous approach to signal preparation and delivery, including delayed voltage activation post-remote start, ensures that FOS1 is trusted for displacement measurements where even slight inaccuracies can compromise system effectiveness—a critical advantage in automotive, robotics, and process automation industries.
