The Genius PowerTRAC block is used in many types of power monitoring and industrial applications. The PowerTRAC block monitors current and voltage inputs and stores digitized waveform values for each input. From these values, the block calculates RMS voltage, current, active power, reactive power, KWH, and power factor. The block automatically sends this calculated data to a host PLC or computer approximately twice per second. The same data can be displayed on a Genius Hand held Monitor, either locally or from any connection point the bus. A PowerTRAC block can be used with a wye or delta configured three phase power system or with a single phase power system. It accepts voltage inputs from one to three potential transformers, and current inputs from up to three line current transformers, plus a neutral current transformer. The PowerTRAC block: Accurately measures RMS voltage, current, power, VARs, power factor, watt hours, and line frequency, even with distorted waveforms. Provides simple user connections. Has low current transformer burden (less than 0.5VA). Indicates magnitude of system harmonic content. Detects and captures overcurrent transients. Overcurrent threshold is user configurable. Can be mounted in distribution or process equipment. Can be installed on a Genius bus up to 7500 feet from the host PLC or computer. Can be used in stand alone applications without a host. The block will automatically provide operator displays on a Genius Hand held Monitor. Has an integral power supply, and accepts either 115/230 VAC or 125 VDC inputs. Is software configurable from the host or from a Hand held Monitor. 1 1-2 Genius PowerTRAC Block User s Manual May 1994 GFK-0450D Block Description The block has two parts: a Terminal Assembly, to which all fixed wiring is attached, and an Electronics Assembly. The Electronics Assembly may be inserted or removed without disturbing field wiring or block configuration. Inputs from current transformers and potential transformers are wired to the Terminal Assembly. The Terminal Assembly is also used to connect the block to the communications bus. The Terminal Assembly is normally permanently mounted. Block Dimensions Dimensions of the PowerTRAC block are shown below. DIMENSIONS IN INCHES, CENTIMETERS IN PARENTHESIS The PowerTRAC block is larger than other Genius I/O Blocks. LEDs The OK and I/O Enabled LEDs on the front of the Electronics Assembly indicate the status of the block and of the communications bus. Hand held Monitor Connector The front of the Electronics Assembly also provides a convenient connector for a Genius Hand held Monitor. The Hand held Monitor is used to complete the block s software configuration, and can also be used for monitoring functions during system operation. Block Power Required The PowerTRAC block s universal input type power supply allows it to be powered from either 115/230 VAC (90 265 VAC) at 47 to 63 Hz, or 125 VDC (100 150 VDC) at 35 VA, maximum. 1 GFK-0450D Chapter 1 Introduction 1-3 Specifications Voltage Inputs: Maximum three phases Range 0 to 120 VAC RMS at 47 to 63 Hz Overvoltage range up to 300V peak Burden per input less than 0.1 VA Accuracy of measured voltages 0.25% reading + 0.25% full scale Configurable PT turn ratios up to 327670:120 (2730:1).

Designed in accordance with UL and CSA, ANSI 37.90, NEMA 2 230, IEEE 587 Ordering Information PowerTRAC block IC660BPM100 1 1-4 Genius PowerTRAC Block User s Manual May 1994 GFK-0450D PTs and CTs The PowerTRAC block can be used with one to three potential transformers and up to three current transformers. There must be at least one voltage input with a secondary voltage of 30 VAC to synchronize the PowerTRAC block to the line frequency. However, it is possible to use the PowerTRAC block without any current transformer. Monitoring Current Only The block can be used to monitor current only if at least one voltage input is connected. Special instructions for this are given in appendix C. PTs The PowerTRAC block can be used with any potential transformer having a secondary rating of 120 VAC at 47 to 63 Hz. The block automatically calculates primary voltages up to 327KV (PT turns ratio 2730:1). PTs with higher primary voltages can also be used with the block (see appendix B for details). Voltage inputs are nominally 120 VAC RMS with measurement capability up to 300 volts peak. Accuracy specifications are based on 120 volts full scale. Potential transformers may be connected line to neutral or line to line. CTs Current transformers must have a secondary rating of 5 amps maximum at the PowerTRAC input. The block automatically calculates primary currents up to 32750 amps for line connections or 3275 amps for auxiliary (neutral) connections, although CTs with higher primary ratings can be used (see appendix B). Accuracy specifications are based on 5 amps full scale. For maximum accuracy, you should use the smallest current transformer that will handle the requirements. The block processes current inputs to maximize accuracy and resolution over the nominal 5 amp range with overload capability up to 10x the rated current (50 amps). Current transformer burden is 0.5VA maximum. For safety, CT burdens are permanently connected across the Terminal Assembly s CT input terminals. No spring type contacts are used, and no shorting bars are required for Electronics Assembly servicing or replacement; burden is maintained with the Electronics Assembly removed. |
