Drallim Utilities can offer HV equipment supply and system design guidance, together with on-site installation and commissioning services, and trustworthy technical and service support to meet today’s demanding asset management and business needs. Drallim achieve this by combining their in-house skills in design, manufacturing, software, electrical/electronic engineering and service delivery across a wide range of utility-based applications, to deliver real-time solutions in a cost effective and timely manner. As UK and Ireland representatives for a host of world class overseas partners Drallim Industries are a one stop shop for HV asset management solutions.

The importance of insulation testing often becomes apparent during expensive and unnecessary unplanned outages. High Voltage Inc (HVI) provides a range of equipment for VLF testing up to 200kV peak as well as for DC up to 300kV and power frequency AC testing up to 300kV enabling users to conduct insulation, withstand, PD and Tan δ tests. This includes portable as well as higher power options for proof testing of cables, switchgear, motors, transformers, insulators, generators and other electrical apparatus. The range extends to manual and automatic oil dielectric test sets up to 100kV and to HV dividers.

Full product support and calibration services are offered by Drallim Industries Ltd who are the UK & Ireland representatives of HVI.

Various diagnostic tests can be performed on power and instrument transformers using the DV Power range of transformer test instruments. These include DC current tests (winding resistance measurement and tap changer analysis), as well as AC voltage tests (transformer turns ratio, excitation current measurement, phase angle measurement, vector group detection). DV Power also offer DVtest which is a unique specialised non-intrusive method that enables simultaneous OLTC testing of all three phases in a single pass through the tap positions, which greatly reduces testing time. All DV Power test units are supplied with a standard 3 YEAR WARRANTY and intuitive analytical software.

Transformer Testing

Power transformers are an essential component in UK’s electricity distribution network. Their considerable cost & critical functionality dictate that their condition should be constantly assessed to allow the timely detection of incipient faults. This is easily achieved by monitoring and analysing the dissolved gas levels in the transformer oil using an MTE Meter Test Equipment HYDROCAL instrument. Dissolved Gas Analysis (DGA) is recognised as the most useful tool for early incipient fault detection and its cost effectiveness is understood worldwide. The pre-emptive information provided by the HYDROCAL range can reduce transformer maintenance times, improve safety and help extend operational lifetime.

The DV Power range of circuit breaker test devices are robust and field-portable instruments with local or PC controlled functionality. These instruments are powerful measurement tools for use during manufacturing, commissioning, and scheduled maintenance of circuit breakers and disconnectors. All measured values can be stored for comparison to manufacturer limits and for trend analysis with previous measured results. All DV Power test units are supplied with a standard 3 YEAR WARRANTY and intuitive analytical software.

Circuit breaker testing

Batteries are crucial components in the overall reliability of powerplants, substations, telecommunication systems, generator excitation systems and protection & control systems. The inability of a battery string to provide sufficient voltage/power to protection circuits may lead to catastrophic consequences that cause damage to site equipment, resulting in reduced safety and costly downtime. Listening to the demands of test engineers from around the world, DV Power have developed state-of-the-art battery testing and monitoring solutions to meet IEEE and IEC standards. All DV Power test units are supplied with a standard 3 YEAR WARRANTY and intuitive analytical software.

Battery Testing

Pressurised oil filled cables have proven to be a successful and widely used solution for the underground transmission and distribution of electricity up to 400kV. Many of these cables are still in use today but as they age they begin to leak oil, infringing upon environmental legislation and leading to potential insulation breakdown. Replacement of complete cables is often expensive and difficult, so management of them is often seen as the best solution. Drallim’s OILMON system provides users with a tool to monitor the pressures, temperatures and electric currents associated with these cables to help them reduce their oil losses and maintain safe insulation levels. Its algorithm also provides them with a tool to facilitate planned preventative maintenance, work prioritisation, cable replacement strategy and provides time stamped data records.

Drallim’s Anti-Condensation System (DACS) is a microprocessor-controlled heater that uses Dewpoint Innovation. This intelligent system monitors humidity and temperature and ensures that the heaters mounted within externally located electrical enclosures are only powered up as required to maintain a condensation free environment within them. It has been specifically designed in response to an industry need to improve system reliability and reduce enclosure electricity heating costs with no loss of protection to the other electrical apparatus mounted within the same enclosure during inclement weather conditions. The system comprises a master unit (100W) and up to three 100W slave units and has an attractive payback when compared to continuous heaters.
