20Hz Generator
Signals & Systems India Private Limited
In order to implement a 100 % stator earth fault protection based on subharmonic injection, a 20Hz voltage is injected into the generator star point. The 20-Hz generator SGEN-1001 is used in combination with the Band Pass Filter SBPF-1001 in the Stator Earth fault protection. The injection can be performed by connecting the SGEN-1001 and the SBPF-1001 to the load resistor of an earthing or neutral transformer. If an earth fault occurs in the generator star point, the 20 Hz voltage drives a current through the fault resistance. From the driving voltage and the fault current, the protective relay determines the fault resistance.

Motor Winding Ohmmeter
RMO-M Series
The motor/generator winding resistance test is used to identify open windings, shorts between two windings, short to grounds, connection mistakes or shorted turns. This non-invasive test of winding resistance helps to pinpoint problems regarding windings in stator or rotor part of an electrical machine. Additionally, motor winding ohmmeter has the capability of performing heat run test which will show a change in windings resistance with an increase of temperature.The RMO-M series is designed as an ideal aid in preventive maintenance of electrical motors and generators. They are powerful (up to 100A of test current), portable (8 kg) and generate DC current which is completely ripple-free. This makes measurement very precise with 0,1% accuracy.Three voltage channels make measurement very easy since it is possible to obtain a value of all three winding resistances in one measurement

Core Loss Testers
S30 and S30S Series
Stacks built with punched laminations can have a lot of quality issues. Even though the lamination material is tested in sheet format before any process, that alone is not sufficient to guarantee good quality stators. Wear and tear of the punch, bad welding, bad insulating coating in annealing add to the magnetic losses in the stator. It is always advisable to test the stator core in it's final format before winding to ensure good quality throughout the production batch.

Eddy-Current Dynamometers
WB Series
Eddy-Current Brake Dynamometers (WB Series) are ideal for applications requiring high speeds and also when operating in the middle to high power range. Eddy-Current Brakes provide increasing torque as the speed increases, reaching peak torque at rated speed. The dynamometers have low inertia as a result of small rotor diameter. Brake cooling is provided by a water circulation system, which passes inside the stator to dissipate heat generated by the braking power. The water cooling in the WB provides high continuous power ratings (max. 140 kW). The WB dynamometers have accuracy ratings of 0.3% to 0.5% full scale ( 2% for WB 2.7), depending on size and system configuration. Additional options include: high-speed version, speed pickup, mechanical rotor blocking device, OEM version IS and vertical mounting.
