Before discussing the transformer online monitoring system proposal, which monitoring parameters need to be confirmed first?
Date: July 2, 2026, 14:12:02
- When developing a comprehensive online monitoring solution, one should not start by discussing the “entire system”; instead, one should first identify which parameters need to be monitored.
- The comprehensive online monitoring system for transformers supports monitoring in areas such as partial discharge, vibration, gases in oil, bushings, load current, and oil surface temperature.
- Specific configurations should be determined through consultation based on the transformer type, voltage level, existing on-site systems, and connection requirements.
Transformer online monitoring systems are project-based solutions. If a customer simply asks for “an online monitoring system” when requesting a quote, it is difficult to provide an accurate proposal right away. This is because the monitoring priorities vary from project to project: some focus on gases in oil, others on partial discharge, while others focus on oil temperature, oil level, and oil pressure; some projects require a comprehensive online platform.
Innotongda’s Comprehensive Online Transformer Monitoring System uses a variety of sensors and monitoring units to monitor key transformer operating parameters in real time. Optional monitoring parameters include partial discharge monitoring, vibration monitoring, oil gas analysis, bushing condition monitoring, load current monitoring, oil surface temperature monitoring, core/clamp current monitoring, and fiber-optic/ infrared precision temperature measurement. The scope of monitoring and system configuration must be confirmed based on project requirements. For solution documentation and pricing, please contact Innotongda.
| Monitoring projects | Possible Areas for Monitoring | Points to Confirm During Communication |
|---|---|---|
| localized emission monitoring (LANM) | Ultrasonic, Radio Frequency, and High-Frequency Partial Discharge Sensors | Is Partial Discharge Early Warning Required, and Where Should It Be Installed? |
| Gas in oil | Analysis of the Composition and Concentration of Dissolved Gases in Oil | Single-gas monitoring or multi-gas monitoring? |
| Oil surface temperature | Oil Surface Temperature Sensor | Is there already a thermostat, or is remote transmission required? |
| Core/Clamp Current | Monitor the current in the core and clamps | Should we monitor for grounding anomalies? |
| Casing Condition | Monitor the operating status of the casing in real time | Should it be included in the integrated platform? |
Before discussing the solution, the client must provide the transformer type, capacity, voltage rating, quantity, installation location, existing monitoring devices, and the platform or backend system to which the system is planned to be connected. For retrofit projects, the client must also specify whether a power outage window is available, whether on-site wiring is feasible, and whether the original system will be retained.
If customers are interested in distribution transformers or modular substations, they may also want to learn about the “Three-in-One Transformer Oil Temperature, Level, and Pressure Monitoring Device.” Relevant product models include the IB-YKTCF-OL/OP, which can be used with oil-immersed transformers and modular substations to monitor oil temperature, oil level, and oil pressure, and upload the data to the smart integrated terminal for the service area via RS-485.
If the client does not yet have a clear budget, you can first break down the project into two categories—“mandatory monitoring” and “optional extensions”—for discussion. For example, the parameters of greatest concern to operators—such as oil temperature, oil level, oil pressure, gas in oil, and partial discharge—can be confirmed in batches based on the importance of the equipment. This allows technical staff to determine, based on the confirmed project requirements, whether a standalone unit or a comprehensive online monitoring system is more suitable.
Related FAQs
1. Does comprehensive online monitoring of transformers have to include all items?
Not necessarily. The monitoring criteria should be determined based on equipment risks, budget, O&M objectives, and on-site conditions.
2. What areas does the integrated online monitoring system cover?
Available monitoring parameters include partial discharge, vibration, gas in oil, bushings, load current, oil surface temperature, and core/clamp current, among others.
3. Can oil temperature, oil level, and oil pressure be tested separately?
We can supply a three-in-one oil temperature, oil level, and oil pressure monitoring device; specific configurations will be determined based on on-site requirements.
4. What is required for a renovation project?
Please provide on-site photos, information on existing systems, power outage windows, platform integration requirements, and basic information about the transformers.
5. Can you give me a fixed quote right away?
For comprehensive online monitoring projects, a quote is typically provided only after confirming the monitoring parameters, the number of units, the connection method, and the on-site conditions.
