Seaward Unveils High-Voltage Test Range

Seaward Electronic has announced a range of high-voltage test equipment. The range is designed for the safe and practical detection of voltages on electrical systems in the power generation and distribution, rail network, petrochemical, and electrical service and maintenance industries. The high-voltage safety testing equipment available includes neon and digital voltage indicators, safe discharge units, neon and digital phasing equipment, insulator leakage detectors and current clamps.

The KDIE high-voltage indicators include neon and digital systems to confirm the presence of voltage on earthed neutral electrical circuits up to 33kV. These are supported by a range of high-voltage phasing rods that enable phase comparisons to be made at the point of paralleling two circuits, without the interposition of voltage transformers or secondary wiring circuits. A neon-type instrument is available for use on circuits up to 11.5kV, and digital versions are available for use on systems of up to 15kV and 33kV.

The range of HV indicators and phasing units is supported by a hook ammeter for accurately measuring current flow on overhead power lines, and a large jaw clamp meter for the measurement of current flow through large conductors. In addition to the standard range of test equipment, specialist testers are available for the safe discharge of stored energy in large capacitors and electrically charged equipment. A dedicated airfield ground lighting voltage detector has also been introduced, for proving dead-on AGL systems up to 5kV.

All high-voltage test and measurement equipment in the Seaward range complies with international safety standards and is manufactured in accordance with IEC 61243. As well as specialist carrying cases, a range of accessories is available in support of the main high-voltage test instruments. These comprise proving units, battery chargers, overhead line extensions and bend-end adaptors for specialist switchgear locations.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
