Based on its specifications, this device can be used in various applications. It is especially suitable for resistance measurement on insulating materials such as e.g. cable insulations, foils, textiles, surfaces, insulating liquids, etc. With a test voltage of 45 V, 100 V, 250 V and 500 V the device fulfi ls most test specifi cations such as e.g. DIN 51953, 53482 and 54345.
The guard switching allows single resistance measurements in a triangle wiring. This could be e.g. a two line cable with common shield or the measurement of insulating materials on a guardring measurement cell.
The selection of the measurement range is done manually or automatically. Fast subsequent measurements can be realized by the internal limit value indicator. When the measured value exceeds the limit the limit value indicator switches and activates a potential-free relay output. The megohmmeter is the right instrument for use in laboratory as well as industrial applications.

The S1-552 is an advanced 5kV insulation tester with a high output current and many time-saving features. A large, analog/digital LCD shows resistance valves up to 5 T%u03A9 and incorporated a timer and other test information. The output current, of up to 5mA, speeds up testing by charging capacitive loads quickly.
The 5 and 15-kV Megohmmeters are high-voltage, line operated instruments that can be used on all types of insulation tests ranging from 500 volts to 15 kV.
With over twenty 1-kV models to choose from, selecting the proper Megger insulation tester can appear a bewildering task at first. Actually all the process requires is a little organization. All Megger insulation testers perform essentially the same test in fundamentally the same manner %u2014 accurately and reliably. Refinements and added features, however, separate one model from another in application and operator appeal.

MJÖLNER 200 is designed to measure the resistance of circuit breaker contacts, bus-bar joints, contact elements in bus-bars and other high-current links. The product has been designed with safety, ease of use and versatility in mind. With MJÖLNER 200 it is possible to make measurements according to the DualGround™ method. This means that the test object will be grounded on both sides throughout the test giving a safer, faster and easier workflow.

Circuit Breakers are one of the critical "safety-valves" of electrical systems and basic maintenance procedures are essential to maintain maximum reliability. As the leading producer of circuit breaker test sets, Megger sets the standards of quality and reliability. New technology is incorporated in the circuit breaker test equipment with the launch the DDA (Digital Data Acquisition) series of circuit breaker test sets. The DDA controller utilizes digital signal processing (DSP) technology along with variable firing angle and pulse duration control to bring improved accuracy and flexibility to the curcuit breaker testing arena. Megger test sets are available for every budget and test application.

Testing circuit breakers to ensure proper operation
High voltage circuit breakers are extremely important for the function of modern electric power supply systems. The breaker is the active link that ultimately has the role of quickly opening the primary circuit when a fault has occurred. Many times, the breaker has to perform its duty within a few milliseconds, after months, perhaps years of idly standing by.
Ever since its introduction in 1984 of the first microprocessor based breaker analyzer on the world market, Programma has taken the lead in portable test instruments for high voltage circuit breakers. Over the years, many new user requirements have lead Programma to innovate new solutions to provide test engineers in the field with effective tools for determining the status of circuit breakers.

SVERKER 750/760 features many functions that make relay testing more efficient. For example, its powerful measurement section can display (in addition to time, voltage and current) Z, R, X, S, P, Q, phase angle and cos ö. All values are presented on a single easy-to-read display.
This is the engineer's toolbox.

The stand-by battery system - a vital part
In the event of a power failure, battery systems are often used to provide standby power for important items of equipment such as protective relay systems, circuit breakers and monitoring devices - all of which require standby power during power outages.
Electric power plants are equipped with many different types of battery systems. Here, the pumps that lubricate generator bearings are examples of equipment for which standby power is crucial.
Telephone exchanges must also be kept operating on standby power.
Computer systems depend heavily on standby power. Even a brief power outage can cause critical data to be lost. Recovering from such damage is often very expensive.

A timer is often needed for use with the CSU600A current supply unit or ODEN A primary current injection test
system. Testing relays with SVERKER 650 also requires an extra timer if more than one timing cycle is to be
measured.
Timer TM200 is ideal for these tasks thanks to its precise accuracy, its broad application range and its compact
dimensions. Timer TM200 is the obvious choice for maintenance work in substations
