Gas detectors, both fixed and portable, provide life saving alerts and notice of the presence of potentially fatal gases in working areas. Typically, a fixed gas detector is used as a permanent gas monitoring solution installed in a specific location such as a process area of a control or a plant room.

The area is continuously monitored measuring the concentration of a selection of gases within the air. Fixed gas detectors are used for the detection of flammable gases, toxic gases and for monitoring oxygen depletion levels.

Fixed gas detection uses the latest technology to ensure the safety of plant and personnel at all times. In the event of a gas concentration reaching a preset high level, fixed gas detectors have alarms, lights and indicators that act as a warning signal to alert the user of the gas risk hazard in both safe and hazardous area locations.

Portable gas detectors are, as their name suggests, portable and easy to carry around. They can be attached to clothing or overalls for continuous gas monitoring when moving between zones and sites.

T&D have an obligation to investigate any cable joint or cable termination product failure, but over the years we have been asked more and more to get involved in general cable failure analysis for high voltage HV networks.

undergo un-biased investigations into any failure involving high voltage cable joints and cable terminations regardless of manufacturers or whether heat shrink or cold shrink type.

Below are 5 case studies covering Cable Fault Analysis linked to the cable jointing and terminating of high voltage power cables. Click on the links for more information on each study.

“It is estimated that the Arctic holds around 30% of the world’s undiscovered natural gas and 13% of its yet-to-find oil. This amounts to around 400 billion barrels of oil equivalent, 10 times the total oil and gas produced to date in the North Sea.”

Developing the Arctic could be essential to securing energy supplies for the future, but it will mean balancing economic, environmental and social challenges,” according to Shell.

The search for oil and gas by exploration companies is becoming ever bigger and no corner of our planet is out of reach (or is it?).

Exploration focuses on areas where extreme temperatures are the norm. The Arctic for example has many untapped resources but working in this type of climate poses new challenges to owners and operators with ambient temperatures as low as -60° Celsius.

Manufacturers of equipment for use in these areas have to find solutions which will operate effectively and reliably in such cold weather climates.

New from Filoform is the FiloSeal+HD re-enterable duct sealing system which provides a strong support system using hexagonal tubes which build up like a honeycomb structure to prevent water ingress and gas migration through cable ducts - this includes sealing LV-HV 11kV-33kV power cable ducts and Triplex cables.

Watch, listen and learn how Crowcon, CH4 gas detection specialists, protect people and plant from the gas risks posed by flammable and toxic gas.

Methane is formed by digestion of organic matter

Under ATEX, CH4  becomes flammable at 4.4% of air by volume

In very high concentration (i.e. low oxygen), methane cannot burn

CH4 methane detection is imperative as methane may cause narcotic effects at low concentrations

Methane is lighter than air and it can collect in the high points of enclosed spaces

Pellistors are very sensitive to low methane levels

Above LEL levels, pellistors may “burn out” and do not fail-safe

H2S inhibits pellistors, so infrared sensors may be better

Gas detectors are needed to ensure worker safety against methane gas

Nexans Euromold are world leaders in the manufacture of Screened Separable Connectors to enable the termination of medium voltage power cables onto outer cone bushings of electrical equipment including switchgear, transformers and motors.

The following article enables the correct selection and specification of Nexans Euromold connectors depending on a) cable specification and b) equipment bushing type (A, B, C, D, E or F).

provide an informative overview of the 6 Bushing Interfaces common to MV electrical equipment - this should benefit the electrical design engineer, project manager and cable jointer.

Nexans Euromold Separable Connectors - Features & Benefits

Compact: Fully screened enabling connectors to be installed in close proximity to surrounding steel work and other connectors. Connectors can be touching if required.

Safety: Safe to touch and weatherproof. Euromold connectors offer excellent mechancial strength.

Flexibility: The connectors can be disconnected and re-used making the movement of equipment possible without having to re-terminate cables.

ELECTRICAL SAFETY

T&D Largest UK Stockist – CATU Electrical Safety Equipment For LV HV EHV Electricity Cables, Lines & Substations

The world of electrical safety, insulation and protection is rife with potential hazards and dangers.

Electrical Safety Foundation International has confirmed every 30 minutes during the work day, a worker suffers an electrically induced injury that requires time off the job for recovery. Over the last ten years, more than 46,000 workers have been injured from on-the-job electrical hazards.

Engineers, installers, maintenance and other operatives working on or near HV and LV electrical installations are at risk from the dangers an arc flash, power surge or short circuit can cause.

Cable jointers working on underground cables, linesmen stringing overhead conductors and SAP’s switching high voltage substations all confront daily dangers of electrocution which can only be moderated by a responsible attitude to electrical safety.
