AIAcompact– in-service Acoustic and Electric (UHF) partial discharge measurements on gas-insulated switchgear (GIS), transformers, and cable accessories.

AIA compact can be equipped with circuits for UHF measurements.The instrument is fitted with a battery pack for independent operation up to 3 hours and adapts to a variety of piezo-electric acoustic sensors and is supplied with a versatile sensor fixture. Additionally, the AIAcompact allows partial discharge measurements on external UHF sensors.Acoustic partial discharge measurements can be easily applied on gas-insulated switchgear and other high voltage equipment without the need of interrupting the operation.

UHF measurements on embedded or external sensors are possible with the use of the FCU2, a logarithmic frequency converter, which covers 100 MHz to 1800 MHz. As with the preamplifiers, the AIAcompact automatically detects the FCU2 and changes into the logarithmic display for the UHF detection. To protect the instrument’s hardware it is advisable to connect an input protection unit like IPU2B to the sensor’s output.

AIAcompact offers three display modes, which are selected using dedicated control buttons: SCOPE, METER, and TIME.

SCOPE

In SCOPE mode, the AIAcompact shows the phase-resolved partial discharge signal or pattern. Here, the ‘Freeze’ function allows keeping such a captured pattern for further evaluation or for taking screenshots.

METER

The METER mode offers four bar graph displays showing derived quantities of the captured activity. The graphs display the RMS and the peak PD level, as well as their 50 Hz (60 Hz) and 100 Hz (120 Hz) content. The instrument automatically synchronizes to the line frequency.

TIME

Within the TIME mode, the AIAcompact displays five or ten AC cycles triggered by a partial discharge event. Thus, this display shows the pattern of consecutive partial discharge events and, hence, offers a clear identification of bouncing particles and the severity of their activity.

AIAcompact Options

• AIAcompact software: All captured patterns and displays can be transferred to a notebook via an USB interface using the optional AIAcompact software. Optionally, the software allows acquisition of color PD patterns.
• Gating: Software controlled noise reduction for PD measurements in environments with high frequency disturbance.
• MUX: Built-in 4- or 12-channel multiplexer to split the PD signal and the voltage signal, with individual setup and calibration factor for each channel.

AIAcompact software offering easy-to-use acoustic partial discharge analysis of gas-insulated switchgear (GIS) and other high voltage equipment plus the optional analysis on embedded or external UHF sensors makes the AIAcompact the ideal solution for convenient in-service substation condition assessment.The AIAcompact combines the complimenting acoustical and electrical partial discharge detection for gas-insulated equipment in a lightweight and battery operated instrument. The measurement inputs provide the supply voltage for different preamplifiers  and acoustic sensors. It automatically selects the appropriate operation mode for each test setup. The AIAcompact  comes with a built-in display and can be operated via integrated push-buttons. Measurement data can be stored and transmitted to a laptop or PC for further analysis.

It has been designed to simplify the application and to combine different measurement tasks with one instrument. With the unique concept of the ICMflex instruments, the entire acquisition hardware is placed on high voltage potential right at the position where the signals are. Thus, no signal cables are needed, as the instrument is fully self-contained and battery operated. In case that the instruments are used for measurements in an environment with high frequency (HF) disturbance, they can be equipped with a gating input for effective noise reduction. Every ICMflex instrument is fully remote controlled via Bluetooth or fiber optic communication. Using wireless Bluetooth or fiber optic technology the ICMflex tanδ and partial discharge analyzer family increases operator’s safety and greatly simplifies off-line testing and analysis of distribution class cables and rotating machine stator windings.

Option TD

The tan delta analyzer uses an unbalanced bridge formed by internal shunt capacitors, the reference capacitor and the device under test. Here, the ICMflex software shows tanδ, PF, capacitance, voltage, and frequency.

Option PD

With the option PD the ICMflex software offers a meter display according to IEC 60270 and an oscilloscopic display of the partial discharge activity as well as a colored φ-q-n pattern based on the data received via Bluetooth or fiber optic connection. Placing the quadrupole and acquisition unit on high voltage potential greatly improves the sensitivity and avoids any noise pickup on signal cables.

ATTanalyzer–Accoustic breakdown locator-Effective tool to locate breakdown during the commissioning of GIS and GIL

 ATTanalyzer is a simple and effective stand-alone tool to aid in commissioning tests of gas-insulated switchgear (GIS) systems and power transformer. The ATTanalyzer reduces delays in commissioning and maintenance by locating flaws in GIS systems and transformers acoustically.Battery-operated acoustic sensors are externally mounted to the GIS and connected via fiber optic cable to the acquisition unit. In case of breakdown, the acoustic sensor transmits an optical signal to the ATTanalyzer, when it has detected the sound wave. The ATTanalyzer then displays the signals received from all sensors versus time like a logic analyzer. Following initial localization of the breakdown’s origin, the acoustic sensors can be repositioned closer to the flaw to further narrow down the location.

Breakdown detection system configuration :

• 1 x ATTanalyzer (4-16 channels max., tbs)
• 1 x ATTanalyzer software
• 4-16 x Acoustic breakdown sensor ATX1

TDAcompact–Tan Delta Measurement Devices-Loss factor (dissipation factor) tan δ analysis

The TDAcompact is a loss factor meter. The capacitance Cx, the tanδ, and the voltage are derived by digitally processing the currents of the test capacitor and a reference capacitor.TDAcompact is a portable capacitance and tanδ analyzer. The focus of the instrument’s application is on the analysis of the epoxy-mica insulation of rotating machines. Besides this, the unit is applicable for oil-paper insulation systems and especially for mass-impregnated cables.TDAcompact simultaneously samples the AC current drawn by the device under test and the current drawn by a reference capacitor. Subsequently, the two current traces are evaluated and the capacitance, the tanδ, and the level of the high voltage are calculated. The unit continuously displays and refreshes these results.Therefore, the instrument does not require any user interaction as with the traditional Schering Bridge, nor does the refresh of the display take that long as with automatic adjusting bridge type analyzers. The basic resolution of the tanδ measurement is 10^-4, which fulfills the requirements for rotating machine testing as well as for testing on mass-impregnated cables.

TDAcompact is designed as a stand-alone instrument. To measure the two currents the basic configuration of the TDAcompact comes with a standard capacitor, that has a built-in shunt capacitor, in combination with an external shunt. Optionally, the unit can be supplied with further shunt capacitors. Generally, the TDAcompact is with digital fiber-optic links to the precision shunts, which allow operation on any potential including the high voltage connection of the device under test. The measuring frequency can vary between 20 and 500 Hz or is fixed to 0.1 Hz (VLF). Upon request, Power Diagnostix can supply complete portable tanδ testers including the high voltage transformer.

RIVmeter  for the measurement of radio influence voltage

RIVmeter is an instrument for the measurement of radio influence voltage (RIV) according to the relevant standards (IEC CISPR 18-2:2010, NEMA 107-1987, ANSI 63-2-1996, VDE 876, DIN EN 55016-1-1). The instrument has a bandwidth of 9 kHz and a tunable center frequency of 10 kHz to 10 MHz (crystal controlled synthesizer). Technically, the RIVmeter is a selective μV-meter. However, the meter reading is weighted according to the CISPR weighting curve, whereas the repetition rate has a strong impact on the reading. The RIVmeter is an ideal instrument to replace outdated RIV measurement instruments in a transformer testing lab, for instance.RIVmeter is a double super-heterodyne receiver acting as narrow-band filter. This narrow-band detection allows staying away from external RF noise e. g. in non-shielded laboratories by varying the center frequency of the filter.

Two factors determine the RIV in μV: the transferred charge and the repetition rate of the PD impulse (number of PD pulses per second). Because of this processing, a direct translation of the measured RIV values (μV) into values of apparent charge in pC is in general not possible. Historically, the RIV technique is based on measurement receivers to estimate the disturbance of communication lines. Thus, properties of those instruments then being available became part of the NEMA standards. However, both the 9 kHz bandwidth and the CISPR weighting curve put emphasis on some type partial discharge activity, while they tend hiding others.The calibration of the RIV measurement is done using an RIV calibrator, injecting a sine wave of typically 100 μV into the bushing. The multiplexer of the RIVmeter is used to conveniently determine the correction factor according to NEMA 107-1987 and other standards.
