Instrument Transformers01:23

Instrument Transformers

Instrument transformers, comprising voltage transformers (VTs) and current transformers (CTs), play crucial roles in power substations by providing isolated replicas of current or voltage for measurement and protection purposes. Voltage transformers reduce the primary voltage to levels suitable for relay operation and measurement, while current transformers scale down the primary current. The primary winding of a current transformer often consists of a single turn, achieved by threading the...
Differential Relays01:20

Differential Relays

Differential relays are used to protect generators, buses, and transformers by comparing electrical quantities at different points. When a fault occurs, the difference in current between the two points triggers the relay to operate, opening the circuit breaker. Under normal conditions, the current entering (i1) and leaving (i2) a generator are equal. When a fault occurs, however, these currents become unequal, and the difference current flows in the relay operating coil, causing the relay to...
Transformers in Distribution System01:27

Transformers in Distribution System

Transformers in distribution systems can be broadly categorized into distribution substation transformers and other distribution transformers. They are crucial for stepping down high transmission voltages to levels suitable for distribution and end-user applications.
Distribution substation transformers come in various ratings and typically use mineral oil for insulation and cooling. To prevent moisture and air from entering the oil, some transformers use an inert gas like nitrogen to fill the...

Area of Science:

  • Materials Science
  • Electrical Engineering
  • Sensor Technology

Background:

  • Power transformer oil environments present extreme conditions (high temperature, electric fields, EMI) challenging sensor reliability.
  • Conventional sensors (electrical, FBG) suffer from EMI susceptibility, cross-sensitivity, and poor performance in harsh conditions.

Purpose of the Study:

  • To develop an integrated fiber Bragg grating (FBG) sensor for simultaneous, high-precision monitoring of oil temperature, pressure, and moisture in power transformers.
  • To overcome cross-sensitivity and reliability issues associated with existing sensor technologies.

Main Methods:

  • Designed an integrated FBG sensor with specialized materials and structures for parameter-specific responses.
  • Engineered sensing elements to minimize cross-sensitivity at the physical level.
  • Tested the sensor under simulated transformer oil conditions.

Main Results:

  • Achieved high sensitivity: 17.1 pm/°C (temperature), ~4 nm/MPa (pressure), and 7.775 × 10-4 nm/%RS (moisture).
  • Demonstrated excellent linearity, repeatability, and resistance to cross-sensitivity.
  • Confirmed stable multi-parameter measurement and effective decoupling.

Conclusions:

  • The proposed integrated FBG sensor offers a robust solution for simultaneous multi-parameter monitoring in power transformers.
  • The sensor exhibits potential for reliable online monitoring applications in demanding transformer oil environments.
