M-3410A Intertie/Generator Protection Relay Facilitates standardization for small/medium intertie and generator protection applications The M-3410A Intertie/Generator Protection Relay is a microprocessor-based unit that uses digital signal processing technology to provide up to twelve protective relaying functions for intertie protection or up to eleven protective relaying functions for generator protection.

M-0272A/M-0236B Syncrotran® Motor Bus Transfer System Performs All Necessary Logic And Control Functions for Motor Bus Transfers at Power Plants and Industrial Facilities Automatically Selects Fast, In-Phase or Residual Voltage Transfer Method Transfer may be initiated manually or via protective relays external to the system. System will automatically initiate a transfer, should the motor bus voltage drop below a preset voltage for a preset time. Four isolated output contacts are used to trip and close two breakers. The M-0272A Transfer Logic Controller works in conjunction with the M-0236B Power Transfer Relay for in-phase transfers. Provides for load shedding prior to initiating residual voltage transfers. Eliminates the need for parallel transfers. The Syncrotran® Motor Bus Transfer System is an integrated system that provides for one way and bidirectional Automatic and Manual Transfer of auxiliary motor bus systems between two sources of power in power plants and industrial facilities to ensure continuity of plant operation and processes. The system automatically selects between Fast, In-Phase, and Residual Voltage motor bus transfer methods, based on varying system conditions. The Fast Transfer Method can be selected to operate in either the Sequential or Simultaneous Mode. The Syncrotran System continuously monitors the main or incoming source, the motor bus and the startup or bus tie source to ensure the integrity of the motor bus. The system consists of the M-0272A Transfer Logic Controller and the M-0236B Power Transfer Relay.

M-0236B Power Transfer Relay Synchronous transfer of auxiliary services at a generating plant or the motor load in an industrial plant is highly desirable to prevent either damage to critical motors or an unplanned shutdown. However, a significant induced voltage will remain at the terminals of a rotating machine for a period of time following removal of power. If, during the power transfer sequence, the phase angle of this voltage relative to the auxiliary source is ignored, severe damage to an expensive machine or process may result. The M-0236B Power Transfer Relay provides a high-speed means to synchronously close a transfer breaker onto the disconnected but still spinning motor load, thereby avoiding damage to the machines. The maximum phase error at the instant of breaker closing is determined by slip rate and the breaker closing time.

M-0245C High Speed Sync-Check Relay High speed transfer of auxiliary services at a generating plant or the motor load in an industrial plant is highly desirable to prevent either damage to critical motors or an unplanned shutdown. A significant induced voltage will remain at the terminals of a rotating machine for a period of time following removal of power. If, during the power transfer sequence, the phase angle of this voltage relative to the auxiliary source is ignored, severe damage to an expensive machine or process may result. The M-0245C High Speed Sync-Check Relay provides the means necessary to inhibit transfer if the phase angle is excessive or the line voltage is out of range.

Stand alone control with all the Autodaptive intelligence to control pole-top capacitor banks without making setting changes for seasons, load changes or circuit changes With or without communications capability The control can integrate ANY serial communications media Reduces distribution system losses by switching banks at the appropriate time based on load changes Reduces operational costs, maintenance costs, and has a low first cost Easily integrated with legacy radio systems using RCCS centralized VAr dispatch program Supports PDA/local interface for metering, settings, configuration and data download— avoiding the high cost of laptops for field technicians When used with the M-2937 Communications Accessory, remote control, query, auto-alarm for failed com or blown fuse detection can be realized.

M-2980 CAMP™ Communicating Capacitor Bank Control Provides remote Capacitor Automated Monitoring and Protection (CAMP) Fail-safe chargeover to M-2501B Autodaptive® Capacitor Control for 100% hardware backup in the event of communication loss The control can integrate any serial communications media Direct DNP 3.0 slave for SCADA Level VAr Dispatch program interface Neutral unbalance detection to indicate cap bank problem (unsolicited reporting) Provides remote bypass Capacitor Control operation using two-way communications Capacitor control commands that can be initiated remotely include Auto, Open Bank, Close Bank, Counter Reset and Initialize control System monitoring includes capacitor bank control status, switching status, measured voltage setpoint and limits information, as well as control alarm and capacitor bank report-by-exception failure monitoring Accessories include M-2990 Hardware Mounting kit, and M-2941 BecoEye+ Handheld Infarred Field Communications Device for local communications that include configuration, settings and data download The M-2980 CAMP™ Remote Capacitor Bank Control provides a remote communications interface for the M-2501B Autodaptive® Capacitor Control. The M-2980 provides remote capacitor control, system data monitoring, alarms and failure polling of remote capacitor banks from an RTU or Scada Master running DNP3.0. Interface Physical The M-2980 includes four female meter blade receptacles in an industry standard 100 Amp class meter socket to accept the four meter blades from the M-2501B control. A 5th stab is utilized when the unbalance neutral detection is required. This meter blade receptacles are located inside a NEMA 4X rated weatherproof enclosure that houses the wireless device, as well as power supply and interface circuitry. Infrared The IR link from the M-2980 to the M-2501B control consists of an internally routed optical path. The M-2501B contains an IR port exiting the back of the control through the mounting base, in addition to the traditional IR port exiting the bottom of the control through the Lexan™ cover. The rear IR port communicates with the wireless device using an IR port mounted to the rear of the enclosure. Antenna The M-2980 antennas are matched to the specific wireless device that the unit is equipped with. Power The M-2980 and the attached M-2501B are powered by the VT provided with the switched capacitor bank. The power supply for the radio can be configured for either 12 V or 5 V at 10W and is provided with a 2.0 Amp, fast-acting 3 AG type fuse. The M-2501B Capacitor Control possesses an internal fuse independent of the M-2980. Neutral Current Unbalance Detection (Optional) An optional Neutral Current Transformer can be installed around the neutral lead of the capacitor bank. It is sized to handle any expected imbalanced currents without saturation. The CT for Neutral Current detection input allows for the following options: 100:5 Amp CT 100:1 Amp CT 100 Amps to 0.333 V ac The CTs can be either split-core or solid-core CT can be either wired into the terminal board or to 5th stab of meter base

M-2941 BecoEye+™ Handheld Field Communications Device The M-2941 BecoEye+™ Handheld Infrared Field Communications Device communicates all M-2501/M-2501A/B Autodaptive® Capacitor Control operational commands, setting changes and data retrieval functions. The M-2941 includes an RS-232 serial data port and M-0423 Null Modem cable for uploading (19,200 bps) data records from Blinc'd capacitor controls to a host computer. The unit is powered by one (1) nine Volt battery. The unit also includes a separate 3 Volt Lithium battery (950 mAh) for SRAM backup. Download data storage of up to 130 Blinc records Allows uploading of Status, Voltage and Switch data Windows based Upload Utility allows Blinc records to be viewed on a PC
