Qty. 2: Multi-Amp/Biddle EPOCH-10 Open Delta 3-Phase Protective Relay Test Set Comes with what you see in the pictures. If you don't see it, you probably wont get it. Specifications are from Multi-Amp and may vary slightly due to upgrades, options, or revisions this unit may or may not have. This units are guaranteed to work for 30-days, parts and labor, excluding freight. Using 2 units together creates a Open Delta 3-Phase test system. We do not have the interconnect cables for the 2 units but they came as a set. The Unit's Serial Number Tags Read: Model Number: EPOCH-10 Serial Number: 68688-001/1 and 68688-001/2 Power Requirements: 115 V, 50/60 Hz Link to the Datasheet: Multi-Amp EPOCH-10 Relay Test Set Datasheet Link to the Manual: Multi-Amp EPOCH-10 Relay Test Set Manual Key Features: Microprocessor-based relay test equipment Industry standard IEEE-488 GPIB Cornerstone of protecting relay testing Relay Testing Types: IEEE 50: Instantaneous Overcurrent* IEEE 51: Overcurrent* IEEE 67: Directional Overcurrent* IEEE 67N: Ground Directional Overcurrent* IEEE 21: Distance (Single Phase) IEEE 32: Directional Power (Single Phase) IEEE 40: Loss of Field *: For higher currents (up to 187 amperes) or higher volt-amperes, use EPOCH-20 (600 VA) or EPOCH-II (1000 VA) with the EPOCH-10. Description: The Multi-Amp EPOCH-10 relay test set integrates advanced microprocessor-based technology with decades of experience in the application, design and manufacture of equipment for calibrating protective relays to provide an extremely accurate, versatile and easy-to-use relay test set. Intended for field use at substations and power plants, the EPOCH-10 is a rugged test set. Its versatility makes it ideal for use in the relay shop, in the test laboratory, or on the production line. A single EPOCH-10 provides a variable current output, a variable voltage output, adjustable phase-angle settings, a harmonic generator, and comprehensive control and monitoring circuits. Interconnecting two or three units creates an open-delta three-phase test system, or a complete three-phase test system consisting of six independently adjustable, phase-shiftable outputs, three voltages and three currents. The EPOCH-10 can be used with other members of the EPOCH Family to provide more comprehensive facilities when required. Applications: With the modular design of the EPOCH family, you can select the unit(s) with the capabilities and features required by your present application, and add to your original unit(s) as your testing needs expand. The table lists the different types of relays by IEEE device numbers and the different EPOCH-10 combinations that would be required to test them. When performing automated relay testing with a computer and an EPOCH-10, Multi-Amp PulseMaster software (not included) gives you the option of using the computer to perform timing tests. This eliminates the requirement for a separate timer. The accuracy of a computer-based timing method is approximately ±20 ms with IBM PCs and compatibles. When high-speed or high-accuracy timing is required, use either the EPOCH-30, EPOCH-40 or the EPOCH-V. Specifications: Input Voltage: 115 VAC, ±10%, Single Phase, 50/60 Hz Ouput: Output Frequency: Synchronized to input power source Synchronized to external frequency source (EPOCH-30 may be used to establish the frequency output of the EPOCH-10. Standard EPOCH-30 range is 10.000 to 99.999 Hz. EPOCH-10 full output power is available from 40 to 80 Hz. Beginning at 40 Hz, output power is linearly derated to 50% of output tap and 50% of output power at 20 Hz.) 60 Hz crystal controlled 50 Hz crystal controlled Accuracy: Synchronized, tracks input frequency Synchronized to EPOCH-30 ±10 ppm or 0.00006 Hz at 60 Hz ±0.006 Hz for 60 Hz crystal controlled (±0.01%) ±0.005 Hz for 50 Hz crystal controlled (±0.01%) Output Current: To meet a variety of test circuit impedances, three output ranges are provided.
