  • Page 13: Introduction

    To detect such defects at an early stage and reduce the probability of unexpected stops, the IDM monitors the OLTC torque online, warning of changes in its typical signature that indicate failures in development.

  • Page 14: Main Characteristics

    Tap Changer Torque Monitor With the measurements and calculations of the engineering algorithms, the IDM emits alarms in case of abnormalities, as well as notices of maintenance in advance as programmed by the user, with activation of the output contacts.

  • Page 15: Optional Functions

    Allows connecting a potentiometric transmitter or an mA analog signal for indication of the TAP position of the changer in the IDM. The IDM can use this measurement to simply indicate the TAP position of the changer or to aid in calculations of the changer’s maintenance assistance, another optional function of the IDM. Also allows measuring the line current (IL).

  • Page 16: Basic Philosophy Of Operation

    The IDM conducts the online monitoring of the torque developed by the motor during the various stages of the switching, allowing the detection of mechanical failures in the changer before these reach a level of severity that can cause problems of greater proportion.
  • Page 17 (reversible). Thus, various data acquisition logics can be conducted without the need for duplication or inversion of contacts. The IDM has a self-diagnosis relay, signaling any measurement failure condition, lack of auxiliary supply or internal failure to the device. This contact is also reversible.

  • Page 18: Project And Installation

    3 Project and Installation System Topology The IDM has a basic topology, relating its inputs with its outputs, but depending on the existence or not of the associated optional functions, this topology can have some elements included in its scope. Note that not all optional items may be active at the same time.

  • Page 19: General Considerations

    The temperature sensor (RTDs) must be connected to the IDM Torque Monitor through shielded cable, without interruption of the grid, which must be grounded only at the end connected to the IDM. The RS-485 serial communication must be interconnected by means of a twisted-pair cable, maintaining the grid without interruption up to its end, grounding only one of the ends.

  • Page 28: Figure 9 - Voltage Connection For Single

    Figure 9 – Voltage connection for single-phase AC motors without and with the aid of PT. The IDM’s voltage inputs for the single-phase AC motors support measurements of up to 265V AC or 300V DC. For this, if the motor is supplied with voltages that exceed 265V, use a PT to aid the measurement and then parameterize its ratio according to section 5.4.

    PTs. The IDM’s voltage inputs for the three-phase AC motors support measurements of up to 240V AC or 300V DC. For this, if the motor is supplied with voltages that exceed 240V, use a PT to aid the measurement.

    11) Potentiometric Transmitter: Optional Item 4: Changer Position allows the user to use the IDM to follow up the changer's TAP position. For this, a sensoring must be installed in the changer, and the IDM may read two types of them: potentiometric transmitter and mA analog signal.

  • Page 35: Figure 17 - Connection Of The Tap

    Figure 17 - Connection of the TAP measurement cable shielding The IDM automatically compensates the resistance of the potentiometric transmitter's connection cables up to the AVR, and for such the three wires must have the same length and size, the maximum resistance allowed for each one of the wires being 8.

  • Page 36: Figure 18 - Configuration Of The Potentiometric Transmitter

    The IDM allows the resistance per step of the potentiometric transmitter to be in the range of 4.7 to 20, and the transmitter's total resistance of 9.4 to 1000. value of each individual resistor is shown in Figure 18.
  • Page 37 IDM should only read the current that goes to the motor. To guarantee that the phase is the same of the current and voltage, the CTs must be connected in the same points because there are reversing contactors, responsible for inverting the phases and thus changing the phase between voltage and current.

  • Page 38: Figure 20: Connection Of The Interconnection Shielding Between

    An RTD temperature sensor can be connected to the IDM through shielded cables, without interrupting the grid, which must be grounded only at the end connected to the IDM, as close to this as possible. If there is need for intermediary terminal strips for interconnection of the RTD sensor, also pass the cable shielding through terminal strip, preventing its interruption.

  • Page 39: Output Terminals

    There are two of these relays in the IDM, but in the parameterization they can be configured to function normally as NO or inverted as NC. In the second case, while the IDM is powered up, the relay will function as NC, but if the equipment, or only the relay, is powered down, the contact will open.

Standard Value: 0 5.13.2 RELA Submenu - Relays The IDM has output relays that can be programmed to activate light boards and avan other systems interested in knowing the state of the alarms. In this submenu, the relays can be tested and have their functions programmed.
  • Page 95 MOdE – Relay Mode Relays 1 to 3 may function in NO or NC modes, depending on how electrical installation of the IDM is done. By hardware, relays 4 and 5 are always NO. modE However, the IDM allows the electrical assembly logic to be inverted by firmware norm such that all the relays can function in NO and NC modes.
