Compressors and condenser stations
Secure compression with RCMS
In a compressor or condenser station, a compressor compresses the natural gas in order to compensate for pressure losses. The natural gas is stored at high pressure, and the pressure in the pipeline falls because of flow losses. The compressor is driven by a drive machine at up to 30 MW. These drive machines can be either gas turbines or gearless electric motors. For electric motors, frequency converters are required, which need to be monitored for their insulation levels or existing leak currents.
Pump stations
Pumps with inverters - safety at all frequencies
In order to cover relatively large distances, there are pump stations to pump the oil or gas. Since the pressure in the raw material to be transported is reduced due to flow losses, the aim of the pump stations is to increase pressure again. The pump is powered by gearless electric motors. This means frequency converters are required, and these need to be monitored for their insulation level or any fault current present.

Transporting oil and gas safely over the seven seas
A tanker transports liquids or gaseous materials such as crude oil, oil as a finished product, fuel or liquid gas. Tankers have pumps for unloading and pumping around the load on board. These pumps are powered by gearless electric motors for which frequency converters are required to monitor for insulation levels or existing fault currents. One of the key components of shipping engineering is the main machine with its auxiliary generators, kettle systems, auxiliary diesel and the generators for power generation and loading pumps. The main distribution board on-board the tankers are generally designed as ungrounded systems which are monitored with ISOMETER®s and fault locators.
