It simultaneously monitors up to three transformer winding temperatures, automatically displaying maximum temperature values. Display screens use LED or LCD digital displays with clear character heights, enabling easy reading from 3-5 meters distance for routine inspections. Multi-point monitoring with maximum temperature display ensures accurate hotspot temperature capture, providing reliable protection for three-phase unbalanced load conditions.
4.2 Multi-level Protection Mechanisms
The system provides two-tier protection with over-temperature alarm and over-temperature trip functions. When temperature reaches preset alarm values, тот temperature control instrument triggers audible/visual alarms and outputs alarm signals. If temperature continues rising to trip setpoints, the system automatically disconnects transformer power to prevent incident escalation. Alarm and trip outputs use relay dry contacts rated 5A/250VAC or 5A/30VDC, capable of directly controlling external alarm devices or circuit breaker shunt trip coils.
4.3 Intelligent Fan Control System
The controller’s built-in fan control function automatically starts/stops cooling fans based on temperature. Users can set fan start and stop temperatures, creating temperature hysteresis control to prevent frequent cycling. The fan exercise function periodically activates fans automatically for short durations, preventing mechanical failures from prolonged dormancy. This proactive maintenance feature significantly improves fan reliability and service life.
4.4 Flexible Parameter Configuration
Температурные пороги (fan start/stop temperatures, температура сигнализации, trip temperature) are configurable via front panel keys or communication interfaces with password protection preventing accidental changes. Temperature range correction allows users to fine-tune measured values, with independent correction settings for each sensor channel. The system provides temperature unit switching (°C/°F), display brightness adjustment, and other user-friendly functions accommodating different regional preferences.
4.5 Data Recording and Fault Diagnostics
Transformer temperature monitoring controllers feature automatic fault detection, continuously monitoring sensor status. Upon detecting sensor disconnection, короткое замыкание, or abnormal resistance, the system immediately displays fault codes and triggers fault alarms. Historical recording functions store temperature data, тревожные события, and trip records. This data is retrievable via keys or communication interfaces for post-event analysis and quality traceability.
5. How Many Models of Temperature Monitoring Systems Are Available?

6. What Are the Common Hotspot Faults in Transformers?

6.1 Winding Hotspot Overheating
Winding hotspot overheating is the most common thermal fault in dry type transformers. Causes include excessive load current, poor cooling system performance, blocked ventilation, or localized short circuits between turns. Without timely detection and intervention through системы контроля температуры, sustained overheating causes rapid insulation degradation, potentially leading to catastrophic failure. Датчики температуры PT100 positioned at winding hotspots provide early warning before critical damage occurs.
6.2 Unbalanced Phase Loading
Three-phase transformers often experience unbalanced loading where one phase carries significantly higher current than others. This creates a thermal imbalance where one winding operates at higher temperature while others remain cooler. Single-point temperature measurement can miss this condition. The IB-S201 series monitors all three windings simultaneously, displaying the highest temperature to ensure comprehensive protection regardless of load distribution.
6.3 Неисправности системы охлаждения
Cooling fan failures represent serious risks for transformers relying on forced air cooling. Fan motor burnout, bearing seizure, or control circuit faults can cause rapid temperature escalation. The transformer temperature controller’s fan exercise function prevents mechanical failures through periodic operation. Кроме того, the system monitors temperature trends, triggering alarms if temperatures rise abnormally despite fan operation, indicating potential cooling system malfunctions.
6.4 Влияние температуры окружающей среды
Extreme ambient temperatures significantly impact transformer thermal performance. High ambient temperatures reduce cooling efficiency and narrow the margin between operating temperature and maximum rated temperature. The IB-S201G model’s ambient temperature monitoring enables calculation of actual temperature rise independent of environmental conditions, providing more accurate assessment of transformer thermal stress. This is particularly valuable in regions experiencing extreme seasonal temperature variations.
6.5 Core Hotspots and Magnetic Circuit Issues
Although less common than winding faults, core overheating can occur due to excessive magnetic flux density, core lamination short circuits, or manufacturing defects. Core hotspots are difficult to detect without dedicated sensors. The IB-S201I model’s core temperature monitoring capability enables early detection of magnetic circuit problems before they cause extensive damage. This is especially important for custom-designed transformers or units operating near saturation limits.

10. Часто задаваемые вопросы – Common Questions About Transformer Temperature Monitoring
10.1 What is the difference between analog and digital temperature monitoring systems?
Analog systems (IB-S201E with 4-20mA output) provide continuous current signals proportional to temperature, ideal for integration with traditional control systems and requiring simple wiring. Digital systems (IB-S201F with RS485/RS232) transmit temperature data via communication protocols, enabling multiple devices on a single bus, remote configuration, and advanced diagnostics. Digital systems offer greater flexibility and information density, while analog systems provide simplicity and universal compatibility.
10.2 How should PT100 sensors be installed in transformer windings?
PT100 sensors should be embedded at the hottest point of each winding during transformer manufacturing, typically at the center of the winding where heat accumulation is greatest. Sensors are usually inserted into pre-formed pockets or channels within the winding structure, secured with high-temperature insulation materials. Lead wires must be properly routed and secured to prevent damage during transformer operation. Для модернизации, surface-mounted sensors can be attached to accessible winding surfaces, though they may not capture true hotspot temperatures.
10.3 Какие протоколы связи поддерживаются?
Standard IB-S201F models support Modbus-RTU protocol over RS485 or RS232 interfaces, the most widely used industrial communication standard. Custom protocol implementations are available through OEM/ODM services including Modbus-TCP, Профибус, ДНП3, IEC61850, and proprietary protocols. Communication parameters (baud rate, data bits, parity, device address) are user-configurable to match existing system requirements.
10.4 Can the system integrate with building management systems (БМС)?
Да, системы контроля температуры трансформатора integrate readily with BMS through multiple methods. The 4-20mA analog output (IB-S201E) connects directly to BMS analog input modules. RS485/Modbus communication (IB-S201F) enables network integration with most modern BMS platforms. Relay contact outputs provide hardwired alarm signals to BMS digital inputs. For IP-based BMS systems, we can provide Modbus-TCP gateways or develop custom Ethernet-enabled versions.
10.5 What is the typical service life of PT100 sensors?
PT100 sensors are extremely durable with operational lifespans exceeding 100,000 часы (над 11 лет непрерывной работы) under normal conditions. Platinum element stability ensures long-term accuracy without significant drift. The limiting factors are typically mechanical connections, изоляционные материалы, and cable integrity rather than the platinum sensing element itself. In transformer applications where sensors are permanently embedded, sensor life typically matches or exceeds transformer service life of 20-30 годы.
10.6 How often does calibration need to be performed?
PT100 sensors and the IB-S201 controller have excellent long-term stability and typically do not require regular calibration during normal service life. Initial factory calibration is traceable to national standards. For critical applications requiring documented accuracy, periodic verification is recommended every 2-3 years using certified reference thermometers. The controller’s temperature correction function allows field adjustment without removing sensors or returning equipment to factory.
10.7 What happens if a sensor fails?
The IB-S201 controller continuously monitors sensor circuit integrity, detecting open circuits (sensor disconnection), короткие замыкания, or out-of-range resistance values indicating sensor damage. Upon fault detection, the controller displays a fault code, triggers fault alarm relay output, and can be configured to either ignore the faulty channel or execute protective shutdown depending on application safety requirements. The remaining operational sensors continue monitoring their respective windings.
10.8 Can existing transformers be retrofitted with temperature monitoring systems?
Да, retrofit installation is possible though it presents greater challenges than factory installation. Surface-mounted PT100 sensors can be attached to accessible winding surfaces or terminal connections using thermal conductive adhesive or mounting clips.
