FDS-PDC Dielectric Response Analyzer
The most important aging indicator of transformers is the water content in the solid part of the insulation (paper, pressboard). An accurate knowledge about the actual moisture concentration is thus required in order to decide if further corrective action, such as on-site drying, is necessary.
OMICRON's DIRANA determines the moisture content in oil-paper insulations of power transformers, CT's and VT's, bushings and power cables by analyzing the dielectric response. The patented device combines the high frequency advantages of the FDS (Frequency Domain Spectroscopy) method in the upper frequency range with the test speed advantages of the PDC (Polarization Depolarization Current) method in the lower frequency range.
Applications
- Moisture assessment of any oil-paper-insulation, such as power transformers, current and voltage transformers, insulated cables and OIP bushings.
- Capacitance and dissipation factor measurements of power transformers as well as bushings, cables, generator and motor insulations
- Aging detection for bushings even at ambient temperature

As a response to the measurement requirements for any distribution and control board, CIRCUTOR has developed a new electrical power analyzer for three-phase systems: CVM-MINI.
Of course any equipment can measure the main parameters in electrical systems, but the smaller size of the three module, DIN analyser, combined with a large number of advantages, make the CVM-MINI the best option for measurement and energy control solutions:
-Capacity to process more than 213 electrical parameters.
-DIN rail mounting or panel mounting (72X72) using an adapter.
-RS485 communications with Modbus/RTU protocol.
-Easy to build into existing control systems.
-Programming, measurement, recording and control software.
-Universal power supply
CIRCUTOR has built into one single small piece of equipment, the performance of any instrument found on any distribution and control board (protection boards, motor and pump control, overload and earth leakage distribution boxes, etc.), in a size and price which will make any board, no matter how small, be incomplete without the presence of the CVM-MINI.

The EN6100-3-2 standard deals with the limitation of harmonic currents injected into the public mains supply system. Meanwhile, the EN6100-3-3 standard addresses the limitation of voltage fluctuations and flicker in low-voltage supply systems for equipment with a rated current of over 16A. These two standards, which became a mandatory requirement in Europe in 2001, apply to electrical and electronic equipment that have an input current up to and including 16A per phase and that are intended to be connected to public low-voltage distribution systems, such as supply voltages nominally 230V AC or 415V AC 3 phase.

In view of the growing number of factors with a disturbing influence on power systems and the ever increasing sensitivity of the devices and installations on the consumer side, simple monitoring criteria such as undervoltage or overcurrent are usually inadequate nowadays. Reliable logging of all the relevant events within the electrical power system calls for the constant observation of a wide variety of derived parameters such as harmonic content, system unbalance or interharmonics and the swift identification of the slightest deviation from the standard state.
In addition to providing pure monitoring functions, modern power system analysing equipment should be capable of logging in full the mode of operation and the interaction of all the component parts of a power supply system.
Only comprehensive and continuous monitoring of the entire power system enables all resources to be used purposively and effectively for the restoration of system operation should a disturbance occur.
In addition, the recorded data provides the planners of electrical installations and protection equipment with an invaluable basis for the extension and optimisation of primary and secondary equipment.
If you are not already convinced of the importance of using a modern power system monitor, you certainly will be as soon as you are confronted with the question of who is liable for system disturbances and who is responsible for meeting the costs involved.
