Monitoring and Control Features

Apply flexible I/O options to meet the many needs of new or retrofit transformer installations. The SEL-2414 includes four slots for plug-in I/O cards. Use digital inputs (DI) to monitor critical transformer alarms and status points. Use analog inputs (AI) to measure pressure, oil level, temperatures, tap positions, and process-level signals (e.g., 4–20 mA, 0–1 mA) from transducers. Operate cooling fans, equipment, alarms, or provide indication with relay-contact or solidstate digital outputs (DO) and analog outputs (AO). Measure ac currents and ac voltage to calculate three-phase power, demand, energy, save in oscillographic reports, and for automatic control processes.

#### Analyze Transformer Event Waveforms

Record analog and digital waveforms at 32 samples/cycle for as many as 64 power system cycles, approximately 1 s. Use the event report to move the oscillographic data to your PC. You can plot your event report data with the SEL-5601 ACSELERATOR Analytic Assistant® Software or with Microsoft® Excel®.


Event reports contain ac currents, ac voltages, and digital inputs and outputs. The report automatically adjusts content to the I/O cards you use. Reports are stored in nonvolatile memory to protect your data even if power is lost. Event reports are optimized for recording power disturbances and relating them to your process.

Figure 7 Example SEL-5601 Waveform Plot

Set the report to capture either 15 or 64 power system cycles of data around the trigger event. For a 60 Hz system, the event report lengths are 0.25 seconds and 1.07 seconds. For a 50 Hz system, the report lengths are 0.30 seconds and 1.28 seconds.

#### Trend Transformer Temperatures and Other Analog Inputs

Record measured ambient, transformer top-oil, transformer hot-spot and other analog data (measured or calculated) for trending with the Analog Signal Profile function. This profile (trending) function can track as many as 32 analog channels. The function records the magnitude and time of acquisition of each analog channel. Use the profile report to move trend records to your PC and quickly plot the data with Microsoft Excel or any other spreadsheet application.

#### Transformer Thermal Monitoring

Transformer thermal modeling per IEEE C57.91-1995 for mineral-oil immersed transformers is a standard feature in the SEL-2414. Specify the SEL-2414 to provide this capability for monitoring and protection of a single three-phase transformer, a three-phase transformer with tertiary windings (three-winding mode with separate CT ratios), or three independent single-phase units. Use the thermal element to activate a control action or issue a warning or alarm when your transformer overheats or is in danger of excessive insulation aging or loss-of-life.

.001,-0.001,"1179"

Figure 8 Comma-Separated File Format for Easy Display, Analysis, and Archiving

Use the thermal event report to capture current hourly and daily data about your transformer. Operating temperature calculations are based on load currents, type of cooling system, and actual temperature inputs (ambient and top-oil). Use as many as four thermal sensor inputs: a single ambient temperature transducer and one transducer for top-oil temperature from each of three singlephase transformers. Temperature data are obtained via an internal RTD/thermocouple card or from an external SEL-2600A RTD Module. While the SEL-2414 can receive temperature data at any rate, the thermal element uses the temperature data once per minute.

The thermal element operates in one of three modes, depending upon the presence or lack of measured temperature inputs: 1) measured ambient and top-oil temperature inputs, 2) measured ambient temperature only, and 3) no measured temperature inputs. If the device receives measured ambient and top-oil temperatures, the thermal element calculates hot-spot temperature. When the device receives a measurement of ambient temperature without top-oil temperature, the thermal element calculates the top-oil temperature and hot-spot temperature. In the absence of any measured ambient or top-oil temperatures, the thermal element uses a default ambient temperature setting that you select and calculates the top-oil and hot-spot temperatures. The device uses hot-spot temperature as a basis for calculating the insulation aging acceleration factor (FAA) and loss-of-life quantities. Use the thermal element to indicate alarm conditions and/or activate control actions when one or more of the following exceed settable limits:

➤ Top-oil temperature

➤ Winding hot-spot temperature

➤ Insulation aging acceleration factor (FAA)

➤ Daily loss-of-life ➤ Total loss-of-life

Generate a thermal monitor report that indicates the present thermal status of the transformer. Historical thermal event reports and profile data are stored in the device in hourly format for the previous 24 hours and in daily format for the previous 31 days.

The thermal model can be used even if a current card is not installed. Current magnitude data can be received by IEC 61850 or other communications protocols.

#### Through-Fault Event Monitor

A through fault is an overcurrent event external to the differential protection zone. Though a through fault is not an in-zone event, the currents required to feed this external fault can cause great stress on the apparatus inside the differential protection zone. Through-fault currents can cause transformer winding displacement leading to mechanical damage and increased transformer thermal wear because of mechanical stress of insulation components in the transformer. The SEL-2414 throughfault event monitor gathers current level, duration, and date/time for each through fault. The monitor also calculates a I2t and cumulatively stores these data per-phase. The SEL-2414 through-fault report also provides percent of total through-fault accumulated according to the IEEE Guide for Liquid-Immersed Transformer Through-FaultCurrent Duration, C57.109-1993. Use through-fault event data to schedule proactive transformer bank maintenance and help justify through-fault mitigation efforts. Apply the accumulated I2t alarm capability of the device to indicate excess through-fault current over time.

#### Flexible Control Logic and Integration Features

Replaces Traditional Temperature Gauges

The SEL-2414 is equipped with as many as four independently operated serial ports: one EIA-232 port on the front, one EIA-232 or EIA-485 port on the rear, one fiber-optic port, and one EIA-232 or EIA-485 port option card. The device does not require special communications software. Use any system that emulates a standard terminal system for engineering access to the device. Establish communication by connecting computers, modems, protocol converters, printers, an SEL communications processor, SCADA serial port, and an RTU for local or remote communication. Apply an SEL communications processor as the hub of a star network, with point-to-point fiber or copper connection between the hub and the SEL-2414. Included communications protocols are listed below.

Replace traditional temperature gauges that show the temperature, and the maximum and minimum temperature since last reset. The SEL-2414 Max/Min metering records and time stamps the maximum and minimum temperatures and transformer thermal model quantities.

Replaces Traditional Latching Relays

Replace as many as 32 traditional latching relays for such functions as “remote control enable” with latch bits. Program latch set and latch reset conditions with SELOGIC control equations. Set or reset the nonvolatile latch bits using optoisolated inputs, remote bits, local bits, or any programmable logic condition. The latch bits retain their state when the device loses power.
