High Current Transformers
-
High Current Transformer is designed to elevate and check the temperature of the conductors at high current levels, in order to simulate the current loading conditions found in electrical circuits. High Current Transformer is designed as an open type transformer that uses the test object as its secondary coil or has 1 or 2-turn self secondary winding. The conductors cores' temperature depends on the short-circuit high current caused by the test object. According to the current going through the test object, the test temperature of the conductor will change. The loop temperature is measured by a thermocouple probe which is directly connected to conductor.

Anti-Condensation Heaters
-
Anti-Condensation Space Heaters are designed to maintain the temperature of an electrical enclosure. Anti-Condensation Heaters are used for elimination of water vapor contained inside the enclosures. They also provide frost protection by keeping the internal temperature of electrical enclosure above the freezing temperature. The Anti-Condensation Space (Panel) Heaters prevent condensation through convection.

LV Iron Core Harmonic Filters
-
Nonlinear loads such as power electronics based equipment and electric furnaces are sources of harmonic currents leading to harmonic distortion, which is one of the most important parameters for defining the power quality. Most of the commercial loads such as personal computers, photocopy machines, power supplies, and compact fluorescent lamps; and industrial loads such as AC and DC motor drives inject harmonic currents into the network that they are connected to.

Reduced Voltage Motor Starting Panels by Auto-Transformers
-
Reduced Voltage Motor Starting Panels are designed for starting of squirrel cage induction and synchronous motors. A RVMS Panel reduces the torque by temporarily reducing the voltage and/or current input. It reduces voltage applied to the motor during start up causing lower starting currents from the connected grid.

Primary Current Injection Testers
-
Primary Current Injection Tester is designed for testing protective relay and circuit breakers and also testing the turns ratio of current transformers at high variable currents. A test current is injected into the primary side of a system to determine how the system behaves at particular levels of current. This test makes it possible to determine whether the relay will trip and how long the current needs to flow before the trip is initiated.
