3.6 kV Two-Core Epoxy-Cast Current Transformer
ER-3C
Offering a higher rated current ratio, this medium-voltage, two-core current transformer is suited to the main panel or the motor control panel of a 3.6 kV (max.) power system and can be used with measuring or monitoring instruments, or with protective relays. Araldite® epoxy resin.
Low-Voltage Current Transformer for Higher Current Ratio and Higher Accuracy - Window Diameter up to 160mm
CR-1S Series
Low-voltage current transformers of the CR-1S Series, available in multi-ratio or single-ratio models, offer higher current ratios (800-4000/5A), higher accuracy, and larger window diameters (even to 160mm or 6.3”) for convenient installation over high current busbars. These epoxy-resin-cast low-voltage (720 volts / 600 volts, or 0.72 kV / 0.6 kV) current transformers facilitate wiring while decreasing contact failure rates.
Epoxy-Cast Window-Type Current Transformers for Indoor Application, 3.6 kV
CR-3S Series
2-core & single-core models. Indoor window-type current transformers for the main panel or motor control panel of a MV (≦ 3.6 kV) power system. Good for protection and appropriate for measuring and monitoring instruments. Araldite® epoxy resin.
Coil Molded Single-Phase Voltage Transformers (Potential Transformers), Indoor Use
EP-3SF/6SF Series
Voltage transformers of the EP-3SF/6SF Series are coil-molded, single-phase, indoor-type, medium-voltage, epoxy-resin-insulated potential transformers suitable for power systems of 7.2kV or below. Made with either a laminated core (Model EP-3SF2) or a cut core (EP-3SF5 & EP-6SFK), the voltage transformer has two power fuses attached to the primary side. Specific models from this series can be used as an auxiliary power source for circuit breaker operation — that is, as a control power transformer (CPT), also referred to as a control transformer (CTR), industrial control transformer, or machine tool transformer.
Voltage Transformers (Potential Transformers) as Circuit Breaker Operation Power Source
EPF-3SF1, EPF-6SF2
Voltage transformers EPF-3SF1 and EPF-6SF2 are medium-voltage, indoor-type potential transformers cast in epoxy resin, commonly installed on switchgear (3.3kV or 6.6kV) to serve as an auxiliary power source* for circuit breaker operation. Positioned atop the switch as an operational power source, these transformers can handle relatively high outputs for short durations. Featuring Class-F heat-resistant insulation material for the coils, each voltage transformer is equipped with two power fuses on the primary side to safeguard against overload and short-circuit currents.* Auxiliary power source: In this application, the voltage transformer may also be referred to as a "control power transformer" (CPT), "control transformer" (CTR), "industrial control transformer," or a "machine tool transformer."
Three-Phase Grounding Voltage Transformer (GVT), or Grounding Potential Transformer (GPT), for MV Indoor Applications
EGP-3DF, EGP-6DF
This ground voltage transformer (GVT), or ground potential transformer (GPT), is a three-phase medium-voltage (MV) potential transformer for indoor applications. With a fuse for each phase, this PT (VT) features epoxy-insulated coils and a five-legged (five-limbed) laminated core. This voltage transformer is used with measuring or monitoring instruments, or for ground-fault protection.
