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.

Single-Pole Voltage Transformers (Potential Transformers), or Three-Phase VT (PT) + GVT (GPT)
EPF-10CE, EPF-10DE, EPF-20SK, EPF-20SL, EPF-30DE
Voltage transformers from this series are indoor medium-voltage single-phase epoxy-resin-cast potential transformers suitable for 12kV, 24kV, and 36kV power systems. They are used in conjunction with measuring instruments for system monitoring and analysis or in combination with protective relays. Specific models can be equipped with a combination fuse assembly on the primary side. Additionally, models with a maximum thermal burden of 1000 VA can also function as a power source for circuit breaker operation, meaning they can serve as "control power transformers" or "control transformers," also known as CPT or CTR, or "industrial control transformers" or "machine tool transformers."

12 kV & 24 kV Epoxy-Cast Voltage Transformer (Potential Transformer) or Control Power Transformer, as Power Source for Circuit Breaker Operation and Lighting
EPF-20DZ
This voltage transformer, cast with self-extinguishing epoxy resin, is a medium-voltage, indoor-type, single-phase potential transformer for a 12kV or 24kV power system for measuring and monitoring voltage signals. With a continuous output capacity of 4000 VA (max.), it can also serve in a small substation or a switchgear panel as a power source for circuit breaker operation and lighting equipment*. * Power source for circuit breaker operation and lighting equipment: In this application, the voltage transformer can also be referred to as a "control power transformer" (CPT), "control transformer" (CTR), "industrial control transformer," or a "machine tool transformer."
