Electrical safety testing innovations at MEE

Testing and measurement equipment will be on show at Middle East Electricity.

Specialist instrumentation company, the Seaward Group, will be demonstrating a number of innovative electrical safety testing and precision measurement solutions at Middle East Electricity 2010.

These instruments are used widely throughout the utility, power distribution, rail networks, petrochemical and electrical service and maintenance industries, and are designed and manufactured in line with international safety standards.

Parent company Seaward will be exhibiting its range of high-voltage safety testing equipment, including neon and digital voltage indictors and digital phasing equipment. Included is the KDIE range of high-voltage indicators, including both neon warning and digital reading systems to confirm the presence of voltage on earthed neutral electrical circuits up to 33 kV.

Each unit in the seven product range incorporates high grade PVC tubing and encapsulated resistor chains, and is supplied with a dedicated proving unit for proof testing before and after use. Also included in the Seaward high-voltage range are high-voltage phasing rods that enable phase comparisons to be made at the point of paralleling two electric circuits.

The phasing units can be used effectively without the interposition of voltage transformers or secondary wiring circuits. Within this range a neon-type instrument is available for use on circuits up to 11.5KV. Digital versions are available for use on systems up to 15 kV and 33 kV.

Also on display on the Seaward stand will be the Cropico DO7 range of rugged digital micro-ohmmeters used for highly-accurate, low-resistance measurement in a wide range of industries. Included in the range is the lightweight and versatile Cropico DO7010 micro-ohmmeter.

With a measuring range of 600 µΩ to 60 µΩ, at switchable current levels of 1 A or 10 A, and with 0.1 mΩ and 10 mΩ resolution, this instrument has been developed especially for a range of low-resistance measurement applications. These include the assessment of underground cable joints and earthing and contactor resistance in electricity substations.

Completing the Seaward line-up at the show is the Clare HAL range of Hi Pot testers. These advanced technology testers have been designed specifically to meet modern Hi Pot flash testing and test data traceability demands associated with international quality assurance and product safety standards.

The HAL electrical safety test unit is capable of carrying out AC or DC flash testing and insulation testing in both open- and closed-area test environments. User-friendly controls and programmable options for establishing test voltages, ramping times, leakage limits and other parameters allow complex test sequences to be generated safely and effectively.

The Seaward Group specialises in providing electrical test and measurement instrumentation to enable utilities, private companies and organisations to comply with the regulatory demands of all types of electrical safety legislation and technical compliance standards.
