The company’s remit extends to delivery plus dismounting old and mounting new valves with actuators. SIPOS will collaborate closely with Siemens in the commissioning of complete units.

The application is significant for SIPOS as it confirms the company’s capability to provide a comprehensive partnership service. Commenting, Heinz Mueller, the Siemens Project Manager responsible for delivery of the new control system at Franken said: “We attach great importance to matching components and services from delivery through to commissioning and for the capability of one provider to offer a one source service. ”

Primary reasons cited by Siemens for the selection of SIPOS were the company’s partnership capabilities that extend beyond the supply of actuators. Additionally, SIPOS’ customer service credentials confirmed that the retrofit would be completed within a demanding time frame and led to the appointment of the actuator supplier.

A further advantage of SIPOS’ offer was the technology’s variable speed capability: SIPOS says that its actuators have a unique capability of slowing down before reaching their end position. Siemens said that this feature proved particularly attractive for this application as the solution extends the life of both the valve and its seat.

The innovative IDAX-300 is based on frequency domain spectroscopy (FDS), which is also known as true dielectric frequency response testing. This well proven and dependable technique is now available in a self-contained, field portable unit with USB and LAN communications, allowing convenient, remote controlled testing, data retrieval and analysis.

By using FDS, which involves measuring the capacitance and tan delta/power factor of insulation at multiple frequencies, the IDAX-300 is able to evaluate not only the condition of the oil in a transformer, but also the condition of the solid insulation.

This gives a much more comprehensive and dependable indication of the transformer’s overall health than traditional test techniques. FDS also offers the additional important benefit that tests can be performed at any temperature.

The latest in the range of FDS test sets from Megger, the IDAX-300 is complemented by new software that has been specifically designed for ease of use, and which allows moisture assessment of the insulation in a transformer to be completed in just 18 minutes.

Weighing less than 5 kg and capable of operation from battery or any 50 Hz or 60 Hz supply in the range 90 V to 265 V, the IDAX-300 is equally suitable for use in the laboratory, the workshop or on site. It is supplied in the form of a complete ready-to-use kit that includes the instrument itself, a set of 9-m cables plus other equipment.
