TTMS delivers new Grid Emulator for research on Offshore Wind Energy

DISTURBANCE TO THE MAINS VOLTAGE Modern wind farms are connected to the mainland power grid via long submarine cables with a large parasitic capacity. And they are equipped with a large number of power electronics converters that produce harmonics. Harmonics are deformations of the sinusoidal mains voltage and current. The interactions between these harmonics and the wind farm components create (...)

Electronic load now possible from 0V!

Dissipate at 0 Volt current. That is not possible, I hear you say. That’s right, but H&H has managed to reduce the operating range of a number of models from the PLI series, electronic loads, to an almost short circuit (10 mV). The ZERO Volt models The so-called ZERO Volt models of the PLI series are available from 1.000W (60A) (...)

New 3000A AC power source from Elettrotest

THE NEW 3000A AC POWER SOURCE FROM ELETTROTEST Elettrotest launches the new 3000A-3V AC power source; the TCS: Test Current Supply. The features of this first version of the new TCS family are: Very low current distortion at any load Very high output current stability: <0.1% Continuous operation at rated amperage Output frequency 10-80 Hz Analog and digital interface The (...)

Starter interface makes testing of intelligent battery and battery chargers easier

The successful PLI series, programmable electronic loads, from H&H is now also suitable for testing intelligent chargers. This by adding the optional Starter Interface (PLI16). Most intelligent battery chargers do not start the charging process until a suitable battery voltage or output voltage is detected. With the optional starter interface, the PLI series can be used to start a discharge cycle by (...)

An 800kVA Grid Emulator/Battery Emulator

Impressive. That was the first thing that occurred to TTMS consultant André Handgraaf. An acceptance test of an 800kVA Grid Emulator / Battery emulator. Emulation of an 800kVA AC grid with freely programmable harmonic (up to the 50th) but also voltage dips, imbalance in the three phases and other grid pollution. The same installation can also be switched to a (...)

192 channel datalogger

192 CHANNEL DATALOGGER TTMS delivered a 192 channel datalogger system to one of its customers. The system is intended to measure the voltage and current distribution in a large production machine for the semiconductor industry. The system consists of 12 PCI cards with 16 input channels each, built in an industrial PC. In the PC we placed a 30TB HD system and (...)

The Cinergia GE/EL+ version AC/DC/VPA

You know from us the Cinergia regenerative Grid emulators, the AC loads, the DC power supply, the DC load, the battery emulator and the Power Amplifier. All versatile instruments that allow us to test extensively to certain standards and save quite a bit on energy costs due to the regenerative power of these units. What is new is that you (...)

The ACL series AC Loads from H&H

Höcherl & Hackl introduces the new electronic three-phase AC load: the ACL series. With the ACL series, H&H makes it possible to load three phases of an AC three-phase system with only one device. This allows compact test systems to be implemented without complex wiring of the control electronics. The three load phases can also be connected in parallel to (...)

New models in the MagnaPower TS series

The Magna-Power TS series DC power supplies consist of 250 different models with power ratings from 5.0 kW to 100.0 kW. Available with an output voltage of 0-5 VDC to 0-6000 VDC and an output current of 0-2,700 Ampere. This series is now extended by another 98 models. The new models have power ratings of 5kW, 10kW, 20kW, 25kW, 30kW, (...)
