AEMC Introduces MiniFlex AC Current Measurement Probe Line
The MiniFlex is a compact, flexible ac current transformer composed of a flexible sensor and an electronic module. The flexible sensor permits measurements on conductors where standard clamp-on probes could not be used. It can be installed in confined spaces, places where access is difficult, or even wrapped around irregular shapes.
The lightweight MiniFlex does not use magnetic cores like standard transformers. The transformation principle is based on an air core. It presents virtually no load to the system under test, has a low phase shift, very good frequency response, and cannot be damaged by overloads. The sensor assembly is insulated for 1000V CAT III and 600V CAT IV. The MiniFlex meets EN 61010 and is CE marked.
In addition, the MiniFlex has an mV output proportional to the current measured for direct readings on DMMs, data loggers, oscilloscopes, and power or harmonic meters. TRMS measurements are taken when connected to a TRMS meter. The MiniFlex is insensitive to dc currents and only the ac component of the measured signal is measured.
The flexible sensor is available in lengths of 6" and 10". The battery powered electronic module provides for OFF-LOW RANGE-HIGH RANGE selections with measurements from as low as 0.5A up to a high of 3000A, model dependent.
Applications include: power measurements, measurements on switchboards, measurements on thyristors, switching measurements (disconnecting switch, etc.), and display of control signals.

New 1250 KCML 34.5 kV TRXLP Underground Cable for the Wind Power Industry
Hendrix Wire & Cable offers 1250 KCML underground cable to the wind power industry. The 1250 KCML size is an addition to Hendrix's wind offering. This larger size cable is fast replacing the smaller 1000 KCML cable in the "homerun" portion of the collection grid, it's reported. This size change has occurred as the turbine generation capacity has increased.
The Hendrix 34.5 kV collection grid cables are available in both aluminum and copper conductor. Both full and reduced concentric neutral configurations are available. All cable is manufactured in the USA, made and tested to ICEA/AEIC Standards and is dry-cure, triple-extruded.

Smart Battery Isolator Introduced
Cole Hersee Co. introduces its new Smart Battery Isolator 48525 and 48530. Especially useful for electrical applications, the smart battery isolator prevents loads on the auxiliary battery from draining the starting battery.
The smart battery isolator provides a more flexible solution than traditional isolators, because it is not specific to an alternator type. Additionally, Cole Hersee's smart battery isolator is smaller, lighter and generates less heat than competitive products. Because the smart battery isolator reduces charging system workload by not connecting to the auxiliary battery until the primary battery is charged to 13.2V, there is lower strain on expensive charging components, extending the product life.
No diode efficiency losses occur when using the smart battery isolator, and it also allows bi-directional charging from alternator or from other power chargers/converters. Easy to install, the smart battery isolator also features an LED status indicator and operational start assist. It's available in 85A and 200A versions.
