kyoritsu 3122b high voltage insulation

The Kyoritsu KEW 3122B High Voltage Insulation Resistance Tester is a professional instrument for measuring the insulation resistance of electrical equipment. It is designed for use in a wide range of applications including power plants, factories, and research laboratories. The Kyoritsu 3122B is an analog, high-voltage insulation tester 5kV, capable of testing insulation resistance up to 5000V.

high voltage insulation testers 5000v

One of the key features of this tester is its high-voltage measurement capability. It can measure insulation resistance at voltages up to 5kV, making it suitable for use on high-voltage electrical equipment such as transformers, switches, and cables. The tester also has a wide measurement range with a maximum measurement of 40 GΩ.

In addition to its high voltage sensing capability and advanced features, the KEW 3122B also offers a number of safety features to ensure safe and reliable operation. It has built-in surge protection to protect the tester and devices under test from damage. The device also has a battery level indicator to ensure that the tester is always ready for use.

3122b high voltage insulation testers Features

  •  Designed to meet the following safety standards: IEC 61010-1,-2-030 (CAT III 600V/CAT IV 300V Pollution degree 2) IEC 61010-031 (Requirements for hand-held probes)
  • Suited for heavy-duty electrical maintenance and servicing of industrial installations, cables, transformers, generators, and switchgear where high-voltage insulation tests are required.
  • Dual scales for low and high ranges change automatically. Color-coded scales for easy reading plus LEDs that illuminate in matching color.
  • Hard carrying case furnished as a standard accessory. Houses both instrument and test lead in compact form. Made of plastic, it is highly water resistant.
  • The rated output voltage is maintained down to 0.1GΩ for KEW3121B, and 0.2GΩ for KEW 3122B. This permits accurate measurements of low insulation resistance.
  • Audible high voltage warning at insulation resistance measurement
  • Optional adapter MODEL8324 is available for connection to the recorder and enables cable insulation monitoring. (Option)

Frequency Asked Questions

What is a Megger used for? what is Insulation Tester used for?

A megger or megohmmeter is a device used to test electrical resistance and insulation resistance. This is usually done by sending a high-voltage signal to the object under test, usually a cable or motor. It is important to use a megger to avoid electric shock and equipment damage.
