DC diagnostic insulation testers Regular insulation resistance testing is one of the most cost effective, non-destructive methods of identifying ageing in electrical equipment. With over 60% of equipment failures being ascribed to insulation breakdown, it is a key area to monitor. Diagnostic DC testing is probably the easiest and most convenient method of achieving this due to the small size and weight of the equipment. 5 kV utility insulation resistance tester S1-568 With exceptionally high noise rejection, the fast charging S1-568 offers the full gamut of automatic insulation tests with 8...

40 kV test unit T99/1 The high voltage test unit is portable and powerful, able to generate a DC voltage of up to 40 kV. The T 99/1 is used for testing of cables, cable accessories, plant and installations. It can be powered from an external 12 V battery. 220000 series provides a dependable, safe, lightweight and portable DC voltage source for testing the quality and integrity of electrical power cables, cable installations, motors, switchgear, insulators, transformers and capacitors. Each test set comes in two units, the HV unit and the controller. 220000 series has advanced performance...

DC overvoltage or withstand testing Portable high voltage test set for DC voltage testing of cable and cable installations HV test set 50 kV, HV test set 80 kV and High voltage DC testers are sometimes known as pressure testers or Hi Pots. They are a convenient way to stress the insulation of cables other than XLPE using above-rated voltages to identify any weakness in the insulation and to measure current leakage. This range of three HV test sets is for the DC voltage testing of cables and cable installations in accordance with international standards. Each set consists of a control unit...

AC insulation testers AC insulation testers most closely replicate the normal operating condition for a substation asset. Consequently they provide the most accurate indication of the insulation condition. AC high voltage test system T22/1 This system is of two piece design and offers continuously variable test voltages up to 75 kV. Its performance is expandable to 150 kV AC by the addition of a second transformer. It features built-in overload protection. The test set can be equipped with a rectifier accessory for DC testing up to 80 kV. DC and AC high voltage test system DC and AC high...

AC insulation testers 12 kV AC Tan δ test system Tough yet light and designed to work reliably in high-interference areas, like substation switchyards, Megger’s DELTA4000 series diagnostic insulation systems offer time saving fully automatic power factor/tan delta measurement and tip-up testing. Also provided are facilities for full manual control –including the ability to vary the applied voltage up to 12 kV during testing – to cater for special testing requirements. Accurate and dependable temperature correction, based on the actual condition of the test object, can be applied to results...

10 A micro-ohmmeter with test results storage and downloading DLRO10X Low resistance testing Low resistance testers or micro ohmmeters have many applications. Most are used for testing the integrity of joints, as there can be serious consequences if there are bad connections in critical electrical systems, poor earths, heating in connections, broken rails on the railways, or on aircraft wings. Routine maintenance using low resistance testers, sometime known as Ducter low resistance ohmmeters, can highlight problems before they become catastrophic. The DLRO10X offers a 0.1 jO resolution with...

BT51 Low resistance ohmmeter ideally suited for bond testing applications, i.e. aircraft frames. Four terminal method of measurement ranges 0-20.00 mO and 0-2000 mO. Test current is 2A. The KC series of test leads provide a complete and convenient solution to the problem of finding reliable test leads that are long enough for testing the continuity of lightning protection conductors in wind turbines. KC-series wind turbine test leads are available in 100 m, 50 m and 30 m versions that are equally suitable for use on site or in the manufacturing plant. All lead set versions are 10 A rated....

Contact resistance testing For testing circuit breaker contact resistance in compliance with IEC62271-100, specialist low resistance testers are used with a high output current. For this and other applications that require a higher test current, Megger offers an extensive range of testers that will fit your testing regime. Testing with DualGround™ Deregulation changed the business environment for utilities, switchgear owners and their service companies. It has increased the emphasis on efficiency of operation, maintenance and service levels. Likewise the internationalisation of the business...
