DC link in Energy Iskra Sistemi capacitorsSector Mission Iskra Sistemi mission is meeting the market and customer needs through the product development, supply of services and consultancy as well as innovative system solutions which ensure efficient, environment and user friendly economic management, and supervision in the energy field. Control from the Source to the Consumption The supply of electrical energy occupies an important position in today’s modern world. A successful power system operation requires the use of high-quality secondary equipment, which enables the protection,...

Iskra Sistemi in Energy Sector monitor and predict them in detail using our software. A group of one- and three-phase energy meters measures the consumption of electricity. The consumption of other energy products is measured using data loggers with a modem for remote communication. These data loggers are also appropriate for use in explosion hazard environments. Reliable Transfer of Data The measured physical values are transferred via our communicators and concentrators to a server. The communicators support all of the most widely used methods of communication and data transfer such as...

Quality of Electrical Energy Networks

DC with EN 50160 Power Qualitylink capacitors Standard Why is it important that your power grid is in accordance with EN 50160? The EN 50160 standard specifies the most important voltage characteristics of electricity supplied by the public distribution systems and the limit values where such characteristics can be expected. EN 50160 specifies allowable voltage values at: • Voltage and frequency deviations • Voltage dips, interruptions and voltage unbalance • Overvoltages • Fast voltage changes • Flicker intensity • Harmonics and THD Iskra Sistemi network analyzers let you know when voltage...

Network Analyzers and Measuring Centres Types of Network Analyzers and Measuring Centres Instruments Class A - high accuracy Evaluation of the electricity supply quality in compliance with EN 50160 Accuracy class 0.2 (optional) Harmonic analysis of phase, phase-to-phase voltages and currents up to 63rd harmonic Additional I/O modules with up to 16 digital inputs or outputs, or up to 8 analogue inputs or outputs Additional communication port (COM2) Housing for DIN rail mounting 8 MB local copy of data 8 MB local copy of data MISMART SOFTWARE - 3-tier middleware 3-tier middleware Data...

DC link capacitors Class A Quality Analyzer Iskra MC 774 Quality Analyser Use: The MC774 Quality Analyser can be used as a standalone power quality monitoring device for the detection of local power quality deviations. For this purpose it is normally positioned at the point-of-common-coupling of small and medium industrial and commercial energy consumers to monitor quality of delivered electric energy or at medium or low voltage feeders to monitor, detect and record possible disturbances caused by (unauthorized) operation of consumers. Identification of relevant fixed measuring points is...

Network Analyzer Measuring centres MC 7x4 Use: Meters from MC7x4 series are designed for environments where beside measurement of three-phase electrical power network additional analogue or digital measurements/controls must be made without additional hardware (PLC, OPLC, ...). Meters are housed in enclosure 144 mm x 144 mm. Features • Evaluation of the electricity supply quality in compliance with SIST EN 50160 • Measurements of instantaneous values of more than 140 quantities (U, I, P, Q, S, PF, PA, f, φ, THD, MD, energy, energy cost by tariffs, etc.) • Accuracy class 0.5 (optional 0.2) •...

DC link capacitors Network Analyzer Measuring centres MC 7x0 Use: The meters are intended for measuring, analysing and monitoring single-phase or three-phase electrical power network. The meter measures RMS value according to the principle of fast sampling of voltage and current signals. A built-in microprocessor calculates measurands (voltage, current, frequency, energy, power, power factor, THD phase angles, etc.) from the measured signals. Features • Evaluation of the electricity supply quality in compliance with SIST EN 50160 • Measurements of instantaneous values of more than 140...

Measuring Centre MC 3x0 - Measuring centres Features •Measurements of instantaneous values for more than 60 quantities (U, I, P, Q, S, PF, PA, f, φ, THD, MD …) - only MC330 •4 Energy counters •Accuracy class U, I, P 0.5 (active energy Class 1, optional 0.5s) •Frequency range from 16 Hz to 400 Hz •Up to 2 tariff inputs (option) •Up to 2 pulse or relay outputs (option) •AC or Universal (option) power supply •Graphical LCD; 128 x 64 dots with illumination •Automatic range of nominal current (max. 12.5A) and voltage (option) •User-adjustable display of measurements •Multilingual support (13...

DC link Transducers Measuringcapacitors Analyzers and recorders MT 5x0 Use: Measuring transducers are used everywhere, where measurement of electrical quantities and sending of data/signals to devices is needed for checking and supervising of used energy. They are used for conversion of electrical quantities in single and three phase electrical systems. They can be used in places where you need analogue output quantities as input into another device. They are able to do permanent analysis of electricity supply quality in compliance with the EN 50160 standard. Features • Evaluation of the...
