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 measurement device (sold separately).
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
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
Winding temperature simulation systems can be specified to work with either 1, 2 or 5 Amp CT inputs for transformer load sensing
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
Choose between one or two RTDs within the same 130, in either 100 Ohm (platinum) or 10 Ohm (copper) output
Both systems are designed to provide local and/or remote indication by accepting most Qualitrol bulb, capillary, or RTD based temperature sensing devices
