Sterling SFTL 1000V CAT IV Protection Fused Leads Set

Click here for pricing and full spec

Fused test leads are essential protection where personel is exposed to potentially lethal voltages and short circuit current. Electrical instruments have fuses inside them, but those fuses do not always provide enough protection, especially when used on high energy circuits. The closer the fuse to the connection, the better protection it is providing to the operator. Therefore fused test leads with fuses installed right at the connection point provide the best protection.

MEGABRAS/TENTECH Mi20KVe 20 kV - High voltage insulation tester

The MI-20KVe High-Voltage insulation tester is a truly portable device that allows the measurement of insulation resistances using test voltages up to 20 kV.
It employs a state-of-the-art technology for the safe measurements of insulation resistances up to 4,000,000 MΩ with four test voltages: 5 kV - 10 kV - 15 kV and 20 kV.
Readings are performed through an easy-to-read analogue indicator, having a broad scale.

This equipment is specially well suited to test isolation resistances in transmission lines and medium voltage distribution systems, whether aerial or underground, as it allows to perform testing with voltages near to the operational value. Besides, it is an excellent auxiliary when detecting cable failures.

Ground Resistance Testers

KYORITSU 4105A-H Ground Resistance Tester, 1200Ω, with hard case

Small and lightweight, the Kyoritsu 4105A-H is both dust and drip proof, conforming to the IP54 standard. The instrument is also shock resistant and designed to meet IEC 61010-1 safety standard. The Kyoritsu 4105A-H is supplied with earth resistance test leads, measurement probe, auxiliary spike kit, batteries, a shoulder strap and a carry case.

The Kyoritsu 4105A-H is designed in such a way that the influence of the earth voltage and earth resistance of the auxiliary spikes are neglected under the earth resistance test. A low measuring current of 2mA allows earth resistance tests to be performed without tripping earth leakage current breakers. The 4105A-H also has the ability to measure earth voltage, up to 200V AC.
