RARA Electronics Corporation
RARA manufactures load banks, ranging from small portable units for testing generators to multi-megawatt designs for larger applications. Regular load testing, along with correct battery maintenance, is the best way of ensuring the reliability of standby power systems. It is routine for all newly-installed generating sets to have a load test during the commissioning process in order to prove the performance of the set and all ancillaries-cooling system, exhaust system, switchgear and protection schemes.

WIKA Alexander Wiegand SE & Co. KG
Sulfur hexafluoride (SF6) is an extremely effective electrical insulator for medium- and high-voltage switchgear. For proper insulation, gas density must remain within certain levels. Furthermore, as SF6 is a potent greenhouse gas, it must not escape into the atmosphere. An SF6 gas density monitor warns operators of dropping levels that indicate contamination and/or leaks. WIKA’s SF6 gas density monitors are temperature compensated and hermetically sealed to shield measurements from atmospheric pressure fluctuations and differences in mounting level. Manufactured entirely from stainless steel for reliability and long life, they are fitted with up to three alarm contacts to provide advance warnings when pre-defined limit levels are reached.

ACTAS C160 -
KoCoS Messtechnik AG
Stationary test system for carrying out fully automatic final factory tests, type and function tests on all kinds of switchgear devices, such as circuit breakers, disconnectors or earthing switches, regardless of the type of drive unit. All the electrical and mechanical parameters needed for the assessment of switching performance are measured in real time and evaluated without either the main contact chambers or the drive unit having to be opened. The system has analog and incremental input channels for the acquisition of analog quantities.

Yangzhou Power Electric Co., Ltd
Testing of certain apparatus requires much high voltage or current that a straight AC test system is not sufficient. Thus resonant test reactor with a variable core is needed. The main advantage of such test systems is lower input power and larger output power. The resonant test system is designed to compensate capacitance in the testing circuit precisely by tuning inductance of the test system. AC resonant test system is used for factory testing of middle, high and ultra-high voltage cables, capacitors, generators, motors, power transformers and gas-insulated switchgears.

HiRES -
HIGHVOLT Prüftechnik Dresden GmbH
The digital recorders HiRES are used to measure, store, and evaluate signals from up to 64 sources synchronously. Depending on the sensors used voltages, currents, temperatures, mechanical movements and various other signals can be measured. This measurement system features the ability to capture fast transient processes such as those occurring in impulse current tests on electrical devices or during switchgear testing. The system is also capable of measuring semistationary and periodic events such as DC voltage and AC voltage as well as superimposed semistationary, periodic and transient processes.

Contact resistance measurement is one of the most important and common tests during switchgear manufacturing, commissioning and maintenance stages. Besides switchgear testing, the RMO digital micro-ohmmeters are designed for simple, safe and efficient testing of:disconnecting switches,high-current bus bar joints,cable splices,welding joints,and different high-current links in factory and high-induction field environments.All DV Power RMO micro-ohmmeters use Kelvin’s 4-point measurement principle which is the most convenient for very small resistance measurements. The measurements are accurate and in accordance with international standards for AC high-voltage circuit breakers testing (IEEE C37.09 and IEC 62271-100).Starting from 2003, DV Power has been a trend-setter on the market when our first 500 A micro-ohmmeter weighing only 8 kg (RMO500A / CPM500) was released.Currently, DV Power products portfolio includes 16 models, divided into 3 series:13 portable models: RMO-A (6) and RMO-G (7) series.6 handheld models: RMO-H (6) seriesThe instruments generate a user-selectable and ripple-free test current up to 800 A in an automatically regulated test ramp. Test current ramping significantly decreases the influence of the magnetic transients to measurement.

Coil analyzers and power supply units are portable and lightweight devices intended for use in harsh switchyard and industrial environments. The typical application is switchgear and circuit breaker testing when substation battery is not connected or available. An advantage over substation battery is enabled testing in under-voltage and over-voltage conditions. Furthermore, the stable voltage outputs with a very low ripple (<0,5%) enable an analysis of the coil and motor current graphs recorded with circuit breaker analyzers from different vendors.SAT40AD, POB30AD, and POB40AD are unique devices in the market due to their dual purpose:Power supply for coils and spring-charging motorsTesting circuit breaker’s coils, motor, and auxiliary circuitAll DV Power coil analyzers and power supply units have four separate outputs for opening and closing coils.SAT40AD has two powerful motor outputs (AC and DC) which can withstand up to 40 A inrush current.POB30AD and POB40AD have DC motor output rated up to 30 A and 40 A respectively. With the use of motor outputs, POB and SAT can also be used as a power source or a temporary battery charger.SAT40A II series instruments can be controlled via PC. The DV-Win application software is used to control both SAT and CAT (Circuit Breaker Analyzers & Timers) devices at the same time, making a unique test system for switchgear and circuit breaker testing.
