    ICMmonitor Partial discharge monitor IV.2.2 Monitoring display The monitoring display mode offers two bar graph displays. On top the so-called NQS value, where N = number, Q = charge and S = per second. The NQS value shows the absolute discharge current and is derived by integrating the discharge values e.g., summing up the total charge flow, divided by the time inter- val (Q/t = [As]/[s]).

  • Page 53: Iv.5 Calibration

    ICMmonitor Partial discharge monitor IV.5 Calibration PD measurements refer to the apparent charge and are relative measurements. Therefore, each new installation, changes of relevant quantity (e.g., bandwidth, coupling capacitance etc.) requires a new calibration. This is done by injecting a known PD pulse close to the origin of the real PD source (specimen) and from this calculating the scale factor for the measurement.
  • Page 54 ICMmonitor Partial discharge monitor All calibrators are switched on with the pushbutton On/Off. Both amplitude (Range) and polarity (Pos/Neg) of the single charge pulse per cycle are dis- played and can be adjusted by pressing the corresponding button. The instru- ment is synchronised to line frequency by a photo diode.

  • Page 55: Iv.5.2 Calibration Menu

    ICMmonitor Partial discharge monitor IV.5.2 Calibration menu IV.5.2.1 PD calibration The ICMmonitor offers a calibration menu (CAL M) which can be found as first item in the menu SETUP1. The calibration should be done in the SCOPE display, as all relevant information is available here. However, the menu CAL is not available, when the optional display PROJ (projections), TIME (trending) or SPEC are visible.
  • Page 56 ICMmonitor Partial discharge monitor IV.5.2.2 Automatic frequency spectrum calibration If the active acquisition channel is in SPEC mode, the CAL M menu offers the AUTO menu item. Selecting this item will switch to the automatic frequency spectrum calibration mode. If the SPEC mode is selected for an acquisition channel, the calibration is only valid for the measurement frequency on which the calibration was performed.

    ICMmonitor Partial discharge monitor IV.6 Noise reduction IV.6.1 LLD noise ground (low-level discriminator) Depending on the environment and the measure- ment circuit, different levels of background noise are visible (see Figure IV.12). Since this noise level is usually stable for the whole period (360°), it can be removed by the LLD function (low level discriminator).

  • Page 58: Iv.6.2 Window Mask (Software)

    ICMmonitor Partial discharge monitor IV.6.2 Window mask (software) Some disturbances such as thyristor firing are phase stable. They can be removed by the soft- ware function WIN. This function allows selecting up to 3 windows which blank out pulses occurring in these windows.

  • Page 59: Iv.6.3 Gating With External Sensor (Analogue Gating)

    ICMmonitor Partial discharge monitor IV.6.3 Gating with external sensor (analogue gating) An effective noise reduction is required in case the ICMmonitor is used for PD measurements in an environ- ment with high frequency (HF) disturbance. HF disturbances, which hamper PD detection, and which can be handled by the gating function, are, for instance, radar signals, corona discharge, or thyristor firing.
  • Page 60 ICMmonitor Partial discharge monitor An ICMmonitor offers the following menus for the analogue gating function. They can be accessed only in the ‘SCOPE’ display ‘SETUP1’/’GATE’ menu. While being in the GATE menu, the ‘autogain’ function as well as the automatic change of the active channel is disabled. Push this button to change to the submenu for manual gating (see below).

    ICMmonitor Partial discharge monitor Application examples Rotating machine monitoring Different modes of installation of the couplers apply, depending on mainly the type, design, and size of the device under test. Followed example shows one standard use of the ICMmonitor, the permanent monitoring of a large motor.
  • Page 62 ICMmonitor Partial discharge monitor The noise signal for the analogue gating is picked up from a coupling capacitor by a current transformer CT1. The output of the CT1 is connected to GATE IN, the input of the logarithmic preamplifier RPA6G that is integrated with the ICMmonitor unit.

    ICMmonitor Partial discharge monitor Transformer monitoring V.2.1 Typical setup The following sketch shows an overview of one transformer PD monitoring system, which is a typical configu- ration. Installations, e.g., such as on three single phase transformers, transformers with oil/SF6, or oil/oil bushings may vary a little bit.
  • Page 64 ICMmonitor Partial discharge monitor With some special bushings the test tap connector is under oil and not accessible from outside. In such cas- es it is possible to mount an oil tight N-N feed through connector into the outer metal enclosure. The follow- ing picture shows such a special configuration.

  • Page 67: Commissioning

    ICMmonitor Partial discharge monitor V.2.2 Commissioning The commissioning starts with the erection of the transformer on site. The bushing adapters and coupling units can be connected after assembling of the bushings. After that all signal cables are feed to a central point in close distance to the transformer.
  • Page 68 ICMmonitor Partial discharge monitor Please consider the following important points while calibrating: Keep all connections leads from the calibrator to the bushing terminal and to ground as short as pos- sible to minimise stray capacitances Remove the ground connection from the HV terminal, or keep a minimum distance of the ground connection to the HV terminal of several meters to increase the impedance (L ) between calibration point and grounding point...

  • Page 70: Operation

    ICMmonitor Partial discharge monitor V.2.3 Operation After commissioning of the PD monitoring system, it can be helpful to consider some general rules for the operation of the instrument. The following list shall give a brief overview. Alarm settings: The most prominent question is the one regarding the correct settings of alarm levels. The instrument pro- vides two general alarms that are independent on the active channel, means if an alarm condition is met on one of the eight or four channels the instrument will trigger the relays or will generate a software alarm event.
