Coil Analyzers & Power Supplies
-
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.

OTP-Based Test System
Test System
Power electronics assemblies often cannot be tested using conventional technology for their electrical performance. Due to the adaptability of the instrumentation, the OTP concept offers an ideal platform even beyond the space requirements of several control cabinets. In order to achieve high test flexibility with different assemblies, the system was equipped with three-phase AC sources and AC loads as well as a precise three-phase power meter. DC sources and loads with different current and voltage ranges cover the test of frequent DUT operating parameters. Time-dependent voltage or current signals can be stimulated by an arbitrary generator with power amplifier. General measurements such as current, voltage, frequency, resistance can be carried out flexibly at various test points using the matrix concept. An oscilloscope with RF multiplexer is available for high-frequency measurements such as residual ripple, switching processes, etc.

Solid State Voltage Injector
J2110A
-
While it is possible to obtain high quality injection transformers with bandwidths as wide as 1Hz to 5MHz or more, in some cases this is still insufficient for some tests. For example a typical heater control loop might have a bandwidth of less than 1Hz while some linear regulators and opamp circuits can have bandwidths of up to 100MHz or in some cases even higher. For these applications, a solid state injector can provide the necessary bandwidth. A solid state injector can perform at DC, while the upper frequency limit is dictated by the components selected and the printed circuit board material and layout. It is possible to obtain a solid state injector with a working range of DC – 200MHz, though above 50MHz the interconnection between the injector and the circuit being tested can become quite critical. It is essential that ripple from the injector power supply does not dramatically degrade the dynamic range or the signal to noise ratio of the measurement. The resulting plots are often much cleaner when using a solid state injector than with a transformer injector.
