Grounding Transformers [ZN (Zigzag), ZNyn, YNd(open), Ii0]
-
Grounding Transformers are designed for providing an artificial neutral point for ungrounded three phase power systems. During the line-to-ground faults, grounding transformers provide an easy path to ground faults to limit the fault currents and transient overvoltages.

Sensing Resistors
Resistive Voltage Dividers
-
NGR Sensing Resistors are attached in parallel to the neutral grounding resistor. The sensing resistor allows a protective relay to detect a resistor failure in a continuous manner. Sensing Resistors are used in combination with neutral grounding resistor monitor relays. The relay measures neutral grounding resistance, neutral grounding resistor current and neutral to ground voltage. The relay continuously measures neutral grounding resistor ohmic value in an unfaulted system and it trips on if neutral grounding resistance varies from its calibrated value.

Air Core Line & Load Reactors
-
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.

Air Core Electric Arc Furnace Reactors
-
Arc Furnace Reactors are serially connected reactors that are installed in the supply systems of arc furnace transformers to stabilize arc and limit the unstable arc furnace current and voltage drop which optimize their melting process. These buffer reactors are connected in series to the primary side of the furnace transformer. Typically these reactors are tapped coils and manufactured as per customer'stap requirements.

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.
