QUALITROL 130/Thermal Plate Winding temperature simulation system
Simplify simulation of transformer winding temperatures
.jpg)
Simulates winding temperature by using a proportional current transformer output to power a heating element contained in the well (pocket). Winding temperature is simulated by adding the rise due to the heater output to oil (liquid) temperature. All systems have at least one well for installation of a temperature indicator and/or measurment device (sold separately). Thermal plate is available with up to 3 wells and the 130 series is available with 1 well and up to 2 RTD’s.
Rugged design and corrosion resistant materials provide long, trouble-free life
- QUALITROL Thermal Plates feature heating elements made of an etched nickel alloy grid which is resistant to burning-out, consistent and stable
- Brass wells and die-cast Aluminum cases with thermosetting powder coat provide excellent protection from the elements
Simplify measurement of transformer winding and/or oil temperatures
- Wells (pockets) and temperature probes with integrated heating elements provide an accurate simulation of the winding or hot spot temperature of the transformer based on transformer load, oil temperature, and heat rise constant from the transformer heat run
- Wells and temperature probes can be specified without integrated heating elements to provide accurate transformer oil temperature (Thermal Plate only)
- 130 features a well with an integrated heating element and RTDs to produce a simulated winding temperature directly or by inserting other temperature measurement devices
Flexible options offer solutions for any application
- Winding temperature simulation systems can be specified to work with either 1, 2 or 5 Amp CT inputs for transformer load sensing
- 130 features quick and flexible set up of the winding temperature rise factor with jumper selectable resistance network across the CT input terminals
- Thermal Plates offer up to three wells to more efficiently install complex oil and/or winding temperature monitoring
- Many auto balancing transformers, matching units, and trim resistors are available for other special CT and winding rise requirements. TRA-001 transformer can be used for CT currents up to 10 amps
Designed for use with QUALITROL temperature indicators and monitors
- 130 features RTD outputs for remote temperature indication where it is most convenient
- Choose between one or two RTDs within the same 130, in either 100 Ohm (platinum) or 10 Ohm (copper) output
- 130 can be combined with PT100 converter to produce 4-20 mA output for transmitting signals over long distances
- Both systems are designed to provide local and/or remote indication by accepting most QUALITROL bulb, capillary, or RTD based temperature sensing devices
- Employs a universal probe with adjustable length and various sleeves to adapt to different diameter and length wells
- 103 series RTD’s are available with either Pt100 (platinum 100Ω) or Cu10 (copper 10Ω) for use with QUALITROL Thermal Plate products
- Adjustable Resistor Assemblies allow easy calibration of the Thermal Plate’s heating element to your CT circuit
- The TRA-001 auto-balancing transformer adjusts the input from the current transformer to the acceptable range needed for the heating element to simulate winding temperature
For simulation of transformer winding temperature and/or measurement of oil (liquid) temperature. QUALITROL 130 can be used with a remote temperature sensing device and produces measurements directly with RTDs for remote indication and/or SCADA systems.
