Sat40a II Series -
Amperis sl
The Coil Analyzer SAT40A II series is a powerful tool for testing circuit breakers where a substation battery is not available. It is unique device in the market due to its dual purpose: - It can be used as a stable power supply for coils and spring-charging motors (both DC and AC power supply voltage) during commissioning and maintenance testing. - It is powerful analysis tool for assessing conditions of circuit breaker auxiliary circuit and coils. The Coil Analyzer SAT40A II series has separate DC and AC coil outputs for power supply of opening and closing coils. The output voltage is selectable in the ranges from 10 V to 300 V DC or from 10 V to 250 V AC. The Coils outputs can withstand up to 15 A current. The DC and AC motor outputs can generate from 10 V to 300 V DC and 250 V AC voltage. The motor outputs can withstand starting (inrush) currents up to 40 A. These outputs can also be used as continuous power supply outputs.

AJIT Electronics Co.
The protective devices such as relays, overload coils, circuit breakers must be checked regularly to ensure that, they are always ready to operate correctly. If a fault occurs in the equipment, which they are protecting, routine relay testing will quickly detect the faulty, incorrectly adjusted protection circuits correctly. It is usually necessary to measure its operating time. The micro controller based time interval meter is used for this purpose in all AJIT brand relay testers.

LET-1000-RD -
EUROSMC, S.A.
It allows to perform with sufficient power, all the primary current injections to test the proper function and wiring of all the elements that compose the protection and measuring section in a substation.The regulation system is based on a continuously variable autotransformer (Variac) that supplies to a power transformer that delivers the high current outputs and isolate the main supply from the load. A built-in ammeter and a timer gives the information about the current value and the operation time of the relay or breaker under test.
