Product Categories: Reliable Instrument Transformers Inc Solutions
At Instrument Transformers Inc, we offer a broad range of Current Transformers (CT), Voltage Transformers (VT/PT), and Combined Metering Units designed to suit various power system needs:
| Product | Connection Type | Key Ratings & Types | Typical Applications |
|---|---|---|---|
| Current Transformers (CT) | Series | Secondary currents: 1A, 5A Insulation: Epoxy Resin Cast, Oil Immersed | Ammeters, kWh meters, overcurrent protection |
| Voltage Transformers (VT/PT) | Parallel | Electromagnetic or Capacitor Voltage Transformer (CVT) options | Voltmeters, synchronization, under-voltage protection |
| Combined Metering Units | Integrated | Combined CT and VT in one compact assembly | Space-saving metering solutions for switchgear and substations |
Current Transformers (CT)
CTs are connected in series and step down high currents to standardized low values (1A or 5A). You can choose between durable Epoxy Resin Cast types designed for dry environments or robust Oil Immersed units for heavy-duty applications. These transformers are suitable for energy measurement and protection functions like overcurrent relay triggering.
Voltage Transformers (VT/PT)
VTs (or PTs) work in parallel to reduce high voltages to measurable levels. Options include traditional electromagnetic types and advanced Capacitor Voltage Transformers (CVT), especially useful for higher voltage systems. VTs assist in voltage measurement, system synchronization, and under-voltage protection.
Combined Metering Units
To save space and simplify installation, our combined metering units integrate CT and VT together in one compact device. Ideal for applications where panel space is limited or for streamlined substation setups.

Frequently Asked Questions about Instrument Transformers Inc
Here are answers to common questions about instrument transformers like current transformers (CT) and voltage transformers (VT):
| Question | Answer |
|---|---|
| What’s the difference between metering CT and protection CT? | Metering CTs have low saturation points for high accuracy at low currents (like 0.2S class), ideal for billing. Protection CTs tolerate higher saturation (5P10, 5P20 classes) to handle fault currents without false trips. |
| Are multi-ratio CTs available? | Yes, customization options include multi-ratio CTs allowing different secondary ratings for flexible applications. This helps optimize equipment compatibility and future-proof your setup. |
| What is the typical lead time for custom orders? | Custom instrument transformers usually take 6 to 10 weeks, depending on design complexity and volume. We recommend contacting Kampa engineering early for precise timelines. |
